finding an exhaust leak

TOM90LX · 01-23-2002, 10:29 AM

I just installed BBK h-pipe with cats and when I started the car I had a really bad leak.. the car sounded like a farm tractor.

Is there an easy way to find a leak?

I suspect its the header collector - to hpipe flange..

I'd suspect the header to h-pipe flange.
Get under there and tighten the crap out of them. Mine always need to be really tight to not leak

good luck
