i have a stock 94 ls and there is alot alot of pressure cumin out of the exhaust....i turn ma sisters 00 crv up and she has no pressure cumin out her exhaust..pressure as in blowing air really hard..is this normal for ls motors?? car idles fine at 800

 

You might need to lubricate your muffler bearings..

 

ooo Sh!t...im serious man...its blowing air out like if i would be idling high

 

how many turbos you running? anything over like 2 turbos gives you mad exhaust pressure, like a good way to tell is compare it to a CRV. If you have more exhaust pressure then a CRV then you probbably have gotta be like over 2 turbos

-edit-
oh shit I see you already did the CRV test, damn i guess you got like at least 2 turbos in your exhaust

 

what type of exhaust?

 

Your problem is probably that you have a fart pipe. Switch it with a stock muffler.

 

im runin one turbo on a stock pipe...ma sisters crv is runnin 1 too.....mannnn of course ima compare it to a crv its a 2.0 mine is a 1.8 ...i dont have a fart pipe..stock muffler nice and quiet

 

Your running one turbo, eh?


but

you stated it was stock 94 LS.

 

no im not ...i just said that to be sarcastic...

 

Maybe you should check your EGR valve fluid. Sometimes it tends to get stuck in your catalytic converter causing several symptoms:

1> High exhaust pressure
2> Lack of any grasp of the English language
