Anyone know how to make exhaust quieter after turbo charging. Mine is loud as hell.I have 2.5 all the way back no cat with greddy evo 2 on the end.

 

Find a high flow cat.

 

The reason its so loud is because its straight-piped...get a cat and resonator and you'll see a world of a difference. Yes, turbo cars are more quiet...but not straight-piped.

 

I'm having the same problem with my Cattman headers, test pipe and Apexi WS catback. I'm having a 2.5" b-pipe with a 6"x20" resonator made in a week or two. I'll let you know how it turns out.

 

cool thanks.

 

Turbo, no cat, 2.5" greddy SP and my car is quite, very quite.....until the wastegate opens. The turbo will make a big difference.

 

My car is just overly loud to me it isnt to loud driving or anything. But i would love it to be quieter ,what all do you have exhaust wise mike?I have a straight through with greddy cat back and it is loud.Mine is the greddy evo2, that could be the difference.

 

He just said what he has in his post... turbo, no cat, 2.5" greddy SP.

 

I'm Turbo'd, No Cat, 3 inch custom exhaust, 3x20 inch Luvered Resonator, and 3 inch HKS Muffler. Car is pretty quite while driving, but under low rpm deceleration I do get the occasional burble.

But I would like to get ride of my luvered resonator and get the standard type. Perhaps it will sound a bit different.

 

Neal is that you on streetfire running that vette ?

 

Yes that is me.

 

That was pretty sweet what ems are you running?Engine management becaus ei want to run more boost but need to do some more work. I want to be running 12 psi too. So if you could kinda give me a list of things also what clutch are you running?I am looking in to 550 cc injectors and a walbro but what ems should i look into.

 

greddy emanage blue is my ems, clutchnet 6 puck sprung disk and act PP.

 

Cool thanks Neal keep up the good work by the way keep taking out those zo6's.

 

I will try if my car ever moves from the garage again heh.

 

yeah i think i read that in another thread what happened?

 

stock exhaust plus cutout = best of both worlds more power when you need it and quite when you need it
