Just like the title says. It doesn't matter if the car is in gear or not, when I rev the motor, there is a raspy hiss comming from the passanger side floor. I'm pretty sure it's not an exhaust leak because I had the gaskets replaced when I got my new exhaust put on. It started last night after I raced a Lincon LS V8. If anyone has any opinions they would be welcomed.

 

bump.

 

don't know. (did u beat the Lincoln?)

 

have you tried turning the AC off and reving it to see if the noise persists.....?

 

"Look where the light shines best"

You replaced your exhaust. You now have a noise coming from there. It is reasonable to assume that one of the gaskets has failed since installation. It is common, usually due to inadequate torque at one of the fittings. Easy to check. With the engine running, go put your hand near each of the fittings and feel for an air leak.

 

It was cold as ****, the AC wasn't on, neither was the fan, I've already ruled those posibilities out.

And no I didn't beat the Lincon, they are fast.

 

Thanks, you always give good advice.

 

what kind of exaust are you runnin?

 

it's a Full SS exhaust from the engine back, including manifold.
