86 GW Y pipe delete

Greetings gentlemen, I just picked up a 86 GW with a near perfect body(0 rot) but plenty of other issues. One being a rusted out y-pipe. I was wondering if anyone has done a dual exhaust in place of the Y pipe, and what parts they used for the drop down pipes from the manifolds. After that I can cobble up the rest , unless theres a good not too expensive pre-bent system out there.BTW I wont be replacing the cat. Thanks for any input into this...we'll discuss my many other issues later-lol -George

To run dual is also a pain, and really nothing to be gained in terms of performance. premade Ys are available from the big two. Or maybe you can get an aluminzed one from a muffler shop as I dont recall trying too hard on that route.

When the cat goes you can buy a high flow one from a mail order house. I feel that is worth a little something even on a Jeep that's not going to spin much more than 3500 or 4000 rpm, I hope.

It's a pain on a wag unless you run both pipes down the right side of the wag. Be cheaper/easier to replace the Y pipe and run a single 3" exh down the orig location.
