I installed jet hot longtube headers on my 97 trans am and there seems to be a vibration when car is stopped. Sometimes it will vibrate just for a second when car is 1 sec from a complete stop. I think it touches the lower control arm. Has anyone had this problem? Suggestions and fixes would be greatly appreciated.

make sure the headers are tight, because sometimes just one or two bolts get loose and can make a vibration sound, happened to me, I thought it was the Ypipe touching something, but I torqued the headers again and it went away, you want to go 2 or 3 heat cycles before torqueing them and then they should stay tight

vibration is causing bolts to come loose, but after I tighten them it still touches lower control arm. Anybody have suggestions

only way is to heat it up and bend in the part hitting the control arm or pad the control arm so that it doesn't rattle.

Are you sure you don't have a motor mount loose or broken? Just a suggestion to check.

Yea, sounds like something is broken, or out of shape.

My passenger side header hits the k member ever since I put my th400 with the bmr crossmember. Its a PA tube K member.
