im doing a sleeper so im planning on going turbo but keeping the stock exhaust im going to get the thicker headgasket and fuel managment and a t76 turbo but i want it to sound as stock as possible thats why i want to keep the stock exhaust or either i will go with the comptech supecharger and keep the stock exh. Whats your opinion on this setup i want to get about 350-400 hp max and its a DD

 

Your performance will hinder and you will be at great lost. Get a single 3" exhaust and you'll definitely make more ponies. I know that you want the stock look and sound but you won't be able to get your money's worth from your FI w/ stock exhaust.

 

Also, aren't exhaust temps increased with FI? Running risk of disintegration of your CAT and the the internals of the rest of your piping...including muffler/s. Don't know for sure so don't hold my word towards it.

I would post this in the FI section...will get much better feedback.

 

You could be losing a lot of power potential with F/I and a stock exhaust. If all you're concerned with is a stock look, just build a custom exhaust with bigger piping and stock looking tips.

 

you could just find an aftermaket exhaust that looks stock. GL with finding a quiet one.

 

How about an electric exhaust cut out? You can roll around with less power\stock exhaust and with the flip of a switch open up a straight pipe to unleash the beast. It would get loud but shouldn't be too bad considering turbos themselves are pretty decent mufflers.

T76

What do you think this is a supra motor...GFL with a turbo that size on this engine

 

Don't hinder performance...get one that looks close to stock and good luck.

 

john at inlinePro told me they have dyno'ed a car with stock exhaust making 4xx whp turbocharged of course

 

i am making 321rwhp with a 70mm test pipe and stock exhasut using the inline kit. It sounds quieter than stock
