flutter from exhaust
I have a 2000 Z28 running straights and muffler dumps. When driving, I hear a flutter from the exhaust. Has anyone had this problem before? Let me know your thoughts?
Thanks ,
Bryon

Look the exhaust over for black spots around the welds... also, a cigarette can help, blow the smoke near the suspect areas with the engine running... it will show the leak in the smoke... Same method can be used on a vacuum leak, it will suck the smoke in at the leak.

Had the same thing with mine after I did the header install. Small leak around one of the clamps. I'm going to guess you also removed the AIR and EGR- check the vacumn cap on the back on the back of the intake manifold. Could be the cause of a vacumn leak.

Found the problem! One of the hangers got pushed into my x-pipe and it left a pretty good size hole in it . I hit one of those things at the gas station that you they fill the tanks with, I am pretty sure thats how it happened. Thanks for your help guys.

glad you found it but I was going to ask how you hear anything with that set up.

Are you going to have the hanger re-welded or getting another X-pipe?
