exhaust.

hey SM.. i have a muffler tip n test pipe i was wondering if i could release the cat throw the test pipe n muffler on with the stock downpipe ? or should i just get a downpipe then throw everything on ? sorry im not that well with cars any help is appreciated

What size is the test pipe? If it's a 3" test pipe, redo the exhaust...if it's a 2.5" (or whatever stock exhaust size is), you could find a shop that'll flange the stock cat...then you can swap them out. Although, most will tell you to just do it right and redo your exhuast from the downpipe back. Really though, the stock exhaust isn't worth messing with. I'd sell the test pipe and muffler tip, and put that toward redoing the whole exhaust.

on the turbo supra its a complete waist of time to go with a bigger exhaust with still keeping the stock downpipe....its so effing restrictive that youll see very little if any gain from going with a bigger exhaust!

right now i think its safe to say that BIC makes the best ct-26 downpipes on the market....alone the downpipes from them make 30 almost instant horse power dyno proven...

get a downpipe....then work your exhaust around that.

alright cool guys appreciate the help a lot .. now another question is that if i release both cats i wont be able to pass smog correct ?

 

[KicknAsphlt]

Correct. But, what I'd recommend (and what I've done) is find a shop that will flange a cat for you when you do your exhaust. Then, come smog time, you can go from test pipe to cat in about 10mins, then back again afterward. So far though, I've left the cat in mine...it's WAY quieter, and I haven't really noticed any (or much of) a performance drop. I'll probably play around with this when I get my car back on the road and dyno'd.

i need a turbo 4" inch turbo cat-back exhaust system for my 1992 Supra any suggestions on who makes one for the car or does it have 2 be custom made. I was -just wondering as TRD doesn't stock the part any more.

 

[KicknAsphlt]

Boost Lee had one for sale, dunno if it's sold or not....look for a thread in the 'For Sale' section with 'MDC 4" Exhaust' in it...might be a couple pages back now.

4" is way over kill unless you are shooting for the 800hp range! if you like really effing loud then more power too you but its not needed.

that one guy on ebay makes a 4'' downpipe + cat back for like 600 or something... but i bet it sounds like ass, i've NEVER heard an ebay muffler sound good or last more than 10miles...

 

[CoopMK3]

i don't know if Boost lee's exhaust is still being sold or not last i knew my buddy was buying it... But guess it wouldn't hurt to ask him.

 

[speedysupra]

I will check 4 the boost lee exhaust thanks.
Also was looking at the following option:
A custom made titianium cat-back exhaust with a 5" tip
It's a meisterschaft

 

[CoopMK3]

Yeah IndyMK3 bought that four inch him and i put it on yesterday
