Mr.Gs_GTE

Anybody out there that have or knows where I can get a good cat back exhaust for my gs? I bought a top speed pro system and its too wide for the 93 gs300. Ive been done with my swap and I can't start my car. had it sent to an exhaust shop and they had it for a week only to get a call today telling me that they can't do the job. I really want to get this swap finish and move to the next step. If you have any idea who I can contact or what websites out there have cat back exhaust systems for a JZS147 Please let me know!

I say just go to your local exhaust shop and get a custom 3" set.

why can't you start your car? Stock aristo's come with the same stock exhaust size as the gs. Did the exhaust shop say why they couldn't do the job? Doesn't sound like a very capable exhaust shop, its not a huge undertaking to make a cat-back.

Yea the aristo and the gs300 exhaust are the same from the cat back, but the stock gs300 cat has two different flanges. Like on the stock jz motor the the top of the cat splits up into two manifolds, that mounts to the block. Now on the gte motors there's a single flange that collect flow from both turbos. That's the problem I have right now. I knew I was gonna run 3" all out someday so I just got a new cat back exhaust from top speed and its for the newer gs like 98 and up so its slightly different and with only a few twist and turns it will fit right in but I don't have the equipment to do it @ home. Those fools had the car at a shop, on a lift and couldnt figured it out. BADD SHOP! I did my entire swap on two jack stands and I got around everything for crying out loud. So in the next few days im gonna put the stock exhaust on from mid pipe to the tail and go back and fore on measuring, cutting and having somebody weld it for till I can finish it. Im only gonna have to deal with 'from the down pipe to the midpipe. When I get it all up and running I'll take time to find somebody to do the full exhaust. ****s stressful man for real.. but I'll be aightt right?
