Open exhaust?

[Dink]

I'm just wanting to get an idea for how many guys run their Off Road rigs with no exhaust? Or a form of open exhaust like no muffler, or no cats, or even glass packs or whatever you run just wanting to see what other guys do and how it's worked out for them, good, bad, ugly?

[Artisan]

So you see a lot of guys running open pipes in Glendale ehh?

[rustywagoneers_com]

I hate open pipes.

If my lifters are ticking because all the oil is in one valve cover, I want to know it.

If I have a nasty noise coming from the transmission, t-case, driveline, axles, brakes, wheels, or tires - I want to know it.

I hate - hate - hate - hate - hate open exhaust.

It does not gain you any power.

It makes all wheelers look like idiots to the general public.

I hate open exhaust.

Agreed, a fine tuned exhaust sound traveling up through the gears is a beautiful thing but open loud is just that LOUD. Only thing that gets you is you is annoying people. Save open exhaust for the track.

[Dink]

Artisan I haven't heard anyone out here running open exhaust but I'm still new to the Jeep scene though. Rustywagoneers_com I never thought of it that way, I'm just trying to see what people do have as exhaust right now, I want mine to be loud, but what is a good option for loud without spending a lot of money?

[rustywagoneers_com]

A 3" single flowmaster behind the manifolds sounds good.

Loud is just loud. It eve sucks at the track. A well-engineered muffler won't cost you much if any power. And a missed noise might cost you a WHOLE lot of money.

[lost1]

There were a couple of weeks where I was forced to run with nothing behind the cat. I didn't much like it;setting off car alarms and such is not my idea of cool.

And with modern cats today, I see no reason to delete 'em. Just gives the tree-huggers one more thing to whine about. (whew, I just barely censored myself there! :D )

[Dink]

Rustywagoneers_com flowmasters are a little pricey, I'm looking for pretty cheap as far as exhaust. Does the length of the pipe after the muffler make any difference as to the sound level? Like longer be quieter? Lost1 I'm already used to setting off car alarms with my bike, and also the guy I bought the Jeep from had pulled the exhaust off because he said the cat was messed up so there's just the y pipe left and if I don't have to put cats on it I'm not going to, especially since I might not have to do an emissions test where I'm at.

[rustywagoneers_com]

If you are bucks down then run some 2-1/2" pipe back from the stock y-pipe and hang a 2-1/2" turbo muffler on it.

[Mudwolf]

I'm running dual glass packs. First time I've run them. I really like the sound. Not obnoxious, but loud enough.

[Sean Heep]

I wanted a little rumble without the obnoxious roar. Told my exhaust guy that. Since in Texas, didn't need cat and just installed Edelbrock shorty headers. Went with Turbos after trying Magnaflow and Flowmaster. Cheaper and got the sound I wanted.

[CutterN55]

Shorty headers Custom 2 1/2" Y-pipe to 3" single Flowmaster (40 series?) and dumped in front of rear axle. Everything is nice and high tucked up inside the frame rails. Nice and throaty. Not too obnoxious unless I want to punch it.

[El Jefe]

Before I pulled the 350 I had duals with glass packs. Didn't like it. Just too loud. Its still going to have duals with glasspacks but I doubt the 250 is going to be that loud.

[dan1488]

I have duals all the way no cat with knockoff flowmaster mufflers. I wish it was a little louder. Heck I liked setting off car alarms with my Chevrolet 454.:D

[vintagetrks]

Why do you want your jeep to be loud? The reason I ask is here in Az any and all tree huggers are just looking for reasons to close our trails and one of their main beefs is the noise offroad vehicles make.

[Dink]

Rustywagoneers_com I'm going to look into maybe some Thrush turbos but still want something along the line of Cherry Bombs possibly 24" or so. Mudwolf so glass packs sound pretty good? What size and brand are you running? Sean Heep what turbos are You running? CutterN55 I wouldn't mind Flowmasters but for a little more than the price of a Flowmaster I can build almost an entire exhaust system. El Jefe why was it too loud like as in how? what didn't you like about it? Dan1488 see I know what you're talking about be cause my Harley sets off car alarms when I'm trying to be quiet so it doesn't bother me, I mean if I want to be quiet I'll just drive my Ranger it's nearly silent so yeah. Vintagetrks it might be that I'm young and squirrely and I love the way a V8 sounds with glass packs like my stepdad's truck that I grew up with.

This thread may help some of you, it has links to sounds:

Those of you who haven't posted there, and who have a muffler that isn't included in that thread, please add to it!

[jeeper54]

Unless you have classic car ins. (and drive less than 1k annually and the jeep is valued @ $3500 min.) you'll have to pass emissions and a cat is necessary. BUT...something I did on my 81 cherokee was new high flow cat and then just tailpipe. It sounded good and was a little loud and legal. I latter put my cherrybomb back in because of the exhaust resonating inside. I've had cherrybombs on 3 of my jeeps because they sound good and are CHEAP. Just a thought.

[banjoguy]

I literally just yanked off my old muffler just hours ago on my 87 wagoneer and stuck on a Flowtech Red Hot glasspack. It sounds good and isn't super loud. I actually took it for a ride with the muffler off to go pick up a 90 degree elbow from the muffler shop. Wasn't all that loud inside the cab but my neighbors gave me weird looks.
The glass pack mellowed the sound out. Good deep rumble without annoying the hippies.

If you like glasspacks, I would recommend a Flowtech RedHot, or a Patriot Smithy.

The RedHot I ran on both an XJ with the 4.0 and a Dodge with the 4.7 v8.
Both sounded jsut great; significantly louder than stock but not ridiculous unless you romped on it, and it sounded pretty darn good quality-wise too.

The Smithy is what I'm running now. I opted for the longest-bodied stock pipe one I could find, the 30" case length. It gave me a deep, smooth tone and definitely doesn't sound stock. Since I had to run without a muffler at all for a while, I'd guess that the Smithy took the volume down to about half what it was with open pipe. (the cat on mine is original, and was hollowed out at some point.)

The Redhot was nice, it's aggressive but not annoying. The Smithy, partly due to the much longer than necessary body, is (IMHO) far more fitting of the Wagoneer's aging but powerful stature.

[freeincolorado]

I run 2.5" pipe off the stock Y-pipe to a 40 series Flowmaster with a turn down just before the rear axle and no cat, and it sounds good. It is fairly loud with minimal resonation in the cab. I had been running a 2.5" Thrush glasspack (28" long) and it sounded ok.

[The_Gouge]

40 series and no cat, dumps right before the axle just like freeincolorado.
PO's handiwork. I don't mind it too much, though I always forget how loud it actually is until I pull into my driveway between two houses and then it resonates off of the walls and becomes deafening.
Sounds WAY different than all of the other loud trucks in town, It's a deep note with not alot of bite. It would be perfect it it was a *tiny* bit quieter.

[CutterN55]

Dink- I used a flowmaster because that is what I had. I also had some three inch stainless pipe I re-used. The custom Y-pipe + flanges & having it all put together cost $150. I had it done because I don't have a bender. There are plenty of good flowing mufflers out there with great sound for cheaper than a flowmaster. I really like my setup because I'm not worried about smashing it and it flows well and sounds good.

[710 Burner]

I have given about 1/3 of my hearing to guns and rock concerts. Frankly, I can't afford to loose anymore, and loud mufflers just make my ears ring louder.

[[]V[]AXX]

If you're rock crawling, or muddin, it isn't really that important I guess, but in the woods, you need a muffler or some kind of spark and flame arrester. You CAN start a fire if it's dry enough.

I like powerful, but not painful sounding rides. If I want sweet pain, I'll go watch the fuelies in Gainesville. I missed the Gatornationals this year.:( I agree that if you can't hear anything but the engine, you're an idiot. If you're rock crawlin, and your spotter screams, and you can't hear him, who's at fault?

[Dink]

PlasticBoob that thread has helped A LOT! I've narrowed it down to a Thrush chambered muffler and either a Cherry Bomb glass pack or Flowtech Red Hot. Jeeper54 I'm really considering a Cherry Bomb, and out here there is what is called a code 52 exemption where if the vehicle isn't driven into specified ZIP codes for school or work then you can get the emissions test waived and it's only heavily populated metro areas, which I live well away from and would only be traveling further out of. W7spk from some of the videos on YouTube glass packs sound pretty good on these engines. Lost1 for me I think the Red Hot might be better than the Smithy just because I like it a little louder and I'm sure the longer glass pack would make it quieter. Freeincolorado yeah Flowmaster are out of my mind for what I want, plus I'm leaning way more towards a glass pack anyways. The_Gouge I think that a Flowmaster would be nice but not quite the sound I'm going for. CutterN55 that's part of the reason I want a glass pack because even if I do smash it I can replace it and it'll still be cheaper than a Flowmaster. 710 Burner I understand I've given some of my hearing to my Harley and from working on F-16s but I think glass pack would be alright not quite as loud as an F-16. []V[]AXX I do see your point about a spotter and that's why I think a long glass pack would be alright and it should act as a sufficient spark arrester. I do want to thank everyone on here for being so helpful and giving me so much good advice especially since I'm fairly inexperienced in the mechanical world and even more so the FSJ world I'm extremely new to Jeeps and consider myself lucky to have an FSJ as my first and have so many helpful people out there ready and willing to jump in and give advice, so again Thank all of you!

[El Jefe]

It is just loud. even when you are barely in it you cant have a conversation.

[gvillejeeper]

i like my headers into 2 1/2 pipes through some cheap turbo mufflers then straight up thru the bed into stacks sounds sooo nice:drivin:

[PCDAD]

I run a FlowMaster on my Chev and a Magnaflow on my Wagoneer. Both sound clean and mean, not loud and obnoxious.

[Rod2]

I have outside-the-frame duals with knock-off cherry bombs. I like the sound, but on a coupla' occasions, I dragged one side off while trail-ing and my buddies almost made me shut it down. In N.C., pipes have to exit beyond the sheet metal, so mine bend outward just in front of the rear wheels. Looks good, sounds good.

[vintagetrks]

Vintagetrks it might be that I'm young and squirrely and I love the way a V8 sounds with glass packs like my stepdad's truck that I grew up with.

In that case I say go for some headers and glasspacks. :D Are you at Luke? My son was at Luke a couple years back with the 21st fighter squadren. (The Gamblers)

[duncanstives]

I like my vehiclea as quite as practicle... I take a form follows function appoach: On a funny care that uses "zoomys" (open exuast out the top) to generate downforce its kind of cool... Even on a race car that might need every bit of power and weight savings its ok. Doing it on an offroad rig is dumb and gets old FAST (I knock parts off it regularily by combining an overly heavy foot with narrow debris choked 4 wheeler trails... Driving home with the muffler in the back seat is really annoying.

[jeeper54]

Hey Dink, can you give me some info on code 52 exemption? I used to live just off base and I still had to pass emissions annually. Also, I have a flowmaster 40 (?) w/duals on my Ram 4x4 and it does sound good but when I come home (either one) between 0200 & 0500 I get complaints. I was told that my "neighbors" up north could hear me coming 15 min. before I got there. :rolleyes: And they are much more costly.

[highspdlife0224]

Having owned a dodge with a 5.7 hemi which the p.o. decided to run straights from the cat back, I'll more than likely go with the flowmaster 40 series. I loved the sound of the dodge for the first week or two, but when it began interfering with conversations, it got old. Quick. Plus, everyone knows its you from miles away. Just my .02.:thumbsup:

[Dink]

El Jefe I've decided against open headers and leaning towards glass packs now. Gvillejeeper if I get a J-truck that's probably what I'll do I bet it sounds awesome! PCDAD I'm hoping that a long enough glass pack will sound clean and mean and not too obnoxious but honestly I like obnoxious every now and then that's why I run drag pipes on Bettie (that's my Harley's named after Bettie Page, teenage obsession ;) ) Rod2 mine won't have to be outside the frame or sheet metal so I've got a little bit of free reign there (but I am glad to hear that someone else likes glass packs too!). Vintagetrks yeah I found some long tube Hedman Headers for $165 for my model Jeep so eventually I'll get those and Cherry Bombs are weighing heavily on my mind right now so we'll see, and yes I'm stationed at Luke AFB I started out at the 61st AMU then PCAd to the 62nd AMU I'm right next to the 21st, been here most of my first enlistment just reenlisted 2 weeks ago here comes another 4 years hopefully with at least 20 year retirement as an end goal. Duncanstives well like I said my Ranger is nearly silent and I really like the sound of V8s a lot and the Jeep is a project vehicle that I can have more fun with as far as doing things like glass packs and larger tire and lift and such without feeling guilty, it's not going to be a daily driver but a recreational vehicle as well as creative outlet. Jeeper54 I PMed you some info and I know what you mean my neighbors back home could hear my bike crank with the choke on from over a mile in a heavily wooded place my parents could sit on the front porch and listen to me for over 5 miles away on my way into town for work most of my family miss the sound of Bettie :). Highspdlife0224 I appreciate your 2 cents, and stright pipes are out of my mind on my Jeep but glass packs are under heavy consideration.

This Dink guy is really long winded... ;)

Alright so a new development I just YouTubed Smithy's Mufflers and they sound ridiculously good as Lost1 said they would "The Smithy, partly due to the much longer than necessary body, is (IMHO) far more fitting of the Wagoneer's aging but powerful stature." But my qualm is that I've never heard them in person like Cherry Bombs, Flowmasters, and Thrush turbos, and secondly all the ones on there as Awesone as they do sound they're on a different style of engine flatheads and a Ford Y block engine and I don't know how they'd sound on the AMC 360, so any input would be appreciated! Just an observation this thread has gone from open Headers into a muffler thread haha maybe I should go change the name... which upon further investigation I can't do.

Thrush turbos IMHO have always sounded nice especially if your running headers.
