the first primary where it slips into the rest of the headers on the drivers side...it vibrates and that first primary make an insane racket, at first i thought it was the shield over the brake lines but i removed it and if you touch the first primary with the car running the vibrating noise goes away....any fix for this???

 

Well there's a pretty good chance you have a leak there too. I'm not really sure how you fix that one... I guess you could take it into an exhaust shop and have them tack weld it in place.

 

it doesnt seem to be leaking much...but of course if its ratteling im sure its leaking also...

dont wanna weld it....i condidered a band clamp? problem is i need a 1 3/4 band clamp

 

You may try calling an off-road shop. A lot of dune buggies use small diameter exhaust piping like that....
