Competition Exhaust Question

[FUL POWER]

I keep blowing off my 4" exhaust system right after the down pipe. It happend when im pulling. Right when the turbo lights it here it blow off. I was wondering if there is too much pressure and if i should go with 6" pipe. DOes anyone know where the best place to buy 6" pipe. Thans Scott

Have you tried putting a couple small welds around the pipe?

if i remember right you have a 4 inch flat band clamp, just put a couple fo sheet metal screws in. remember thats what i did when i had the 3 inch straight pipe and it was coming apart. or you could put some big ol stacks on and shoot it towards the sky like me! :-laf
