Well I almost have my car on the road from workign on it for 10 months. I havent ran it much but now that the headers and y pipe are on at low idle in drive it seems to vibrate against the frame. Its edelbrock headers and y pipe. I was wondering if I could put maybe header wrap around that part of the y pipe? its really annoying and want to fix this. Oh ya it doesnt do this if its above 800 rpm or at least I cant hear it anyway.

 

it should NOT be hitting the frame at all. id recheck EVERYTHING to make sure its all lined up. where exactly is it hitting the frame?

 

its hitting right before it curves to connect to the cat. Where its 3 inchs. After the 2 pipes join.

 

could you take a pic??
