I have Gibson headers on my 2007.
The darn things are a thorn in my side and are impossible to keep tight at the flange where the cat and header meet.
First it was the bolts backing out. Solved that with stage 8 bolts.
But now the flange bracket on the cat side has slowly bent so that no amount of torque will keep them from leaking.
I thought about trying a 2 piece replacement flange but I know it will just be a temporary fix.
I could go back to stock headers but A: I dumped too much money into these already and B: I don't want to go back to cracking headers.
Which brings me to aftermarket converters. I see "performance" cats available for a lot cheaper than OEM replacements.
My question is: Will there be enough back pressure for the 3.8?
The metal seems to be higher quality and I'm hoping will be able to withstand more heat.
I'm also open to other suggestions to get these things to stay tight. It's really annoying to have my jeep farting from the front and mor annoying is the power loss.
