NO Exhaust Work for Turbo?
 

Why is it that some shops are telling me to leave my stock piping on my 97 Talon? They say it comes stock with 2.25'' piping, and that 3'' would be too much. I have a t3/t4 turbo being installed with a 2.5'' downpipe, front mount intercooler, etc. Shouldn't I atleast go to 2.5''? Also, the shop says I have to get a custom exhaust b'c it's near impossible to get a pipe to bend for the eclipse. What's up? The exhaust system they offered was $650, can't I get one for $300? Keep in mind I'm keeping my stock muffler.

surely you want to go 2.5 all the way back, do not go smaller than the downpipe, 3" is not to much either. I would go to a few other shops if you havent already, and get other opinions on that nearly impossible theory.

the best exhaust is no exhaust. in turbo cars, bigger is better.

What exhaust shop was this? Yes go 2.5 inches, but I would go with mandrel bent piping because the pressbent 2.5 will probably be less than 2.25 in the bends and kinda defeats the purpose. From what I have seen, all shops in the area use press benders. You can go to rnrracing.com i believe they have cheap catbacks. Also unless you plan on doing somekind of custom modification to your stock muffler I wouldnt use it, that restriction is going to cause a bottleneck and the exhaust gasses are going to build up. Your egts will skyrocket and thats not a good thing. Then again you are going to be at relatively low boost, so it might not make as much of a difference as it would me, since I am running in the neighborhood of 22 psi at the moment.

You can never go with to big of an exhaust on a turbo car. Go to another exhaust shop.

^^ why not?

@ LEAST 3 inches...ive read at least 5 reputable sources that say that. Sport compact car being one of them. I would get even as high as 3 and a quarter to compinsate for crush bends if you go to a local shop.

:stupid: at least 3". downpipe and all. straight-through muffler. getting an exhaust system and putting the stock muffler back on is the most ridiculous thing i've ever heard.

Actually you can go too big on certain setups. I will explain if need be, just let me know.



Pretty much, I was actually thinking about putting a bullet muffler tucked underneath the car and running it back and modifying the stock muffler so it looked stock, but you would definitely hear that it wasnt.

Reasoning
 

The reason why I chose to go with the stock muffler, is because with my last talon, I had an aftermarket muffler on and got 5 tickets in 7 months and I was only cruising around town, never getting on the accelerator. Plus, I read about the 4g63 turbo Hyundai in a magazine that used 3'' piping with a sebring muffler.
