Hissing from the exhaust My car has a hissing noise coming from the exhaust, sounds kinda like a jet
. What could be causing this? It is a very faint sound that you really have to listen to hear it over the Corsa. Any ideas? It made the same sound before I had the Corsa, with just LT's, ORY, and a flowmaster catback. I'm thinking it might be a flat cam lobe, actually I'm hoping it is, so I can get a cam.
Mods are: Hooker LT's, Corsa catback, custom ORY, Lid, cutout, and LS1Edit.
Any questions or need a more detailed description, feel free to ask.
Thanks
Ryan

I thought an exhaust leak is a possibility, but it doesn't seem like such a small leak would make that big of a difference. I dunno, I know I have a very small one, but it is VERY small.

And it sounds like it's coming out of the back of the car, like normal exhaust does. Basically, you don't hear it until the car passes you. And it's only at WOT.
