I couldn't install 2 bolts on my down pipe flange cause one of the bolt holes is being blocked by the dp itself & the other is too close to the block tobe able to tighten with socket, wrench, you name it. exhaust is leaking through these 2 bolts holes, I listened around the flange & it's there. could i plug the holes with jb weld? will it hold permanently?

LOL JB weld it. no jb weld wont work your down pipe will get way too hot. just take the downpipe off and run it open
