Ok guys this is driving me crazy......my truck has one of the slightest exhaust leaks and I can't not for the life of me find it. You can't feel it ANYWHERE AT ALL....the only time you hear it is when its under a load (like when it shifts into OD around 50-55mph and ease on the gas) and its really small, but its still there and annoying as hell. The place where the guy had welded my headers to the Y pipe had a little area he missed so I just put an exhaust clamp over it with that header wrap stuff between. It stopped that leak but now there is a little one....any ideas where it could be from?

Are you sure your not hearing normal header noise? My headers make a noise that sounds like an exhaust leak but it isn't, it is just the way the headers sound...

Ive heard this is normal with the pacesetters since they are thin walled.

It might be but it really sounds like a small exhaust leak....I can only hear it inside the cab though.

Does it go away after you have been driving for a little bit or is it always there?

i hate the way my pacesetters sound haha. I always think i have bad exhaust leaks (my collectors leak bad though, need V-bands)

I can't hear it all the time its just when its under a load....I have no idea its got me puzzled. Its such a small leak it just gets to your head

No it doesn't go away its always there when I hit overdrive and then when I set my cruise it goes away.
