I installed a mac o/r h pipe on stock headers and flowmasters and can't get it to seal up at the catback. Anyone else have issues with this setup?

Did u get the 3 pc o/r H? Mine sealed up good however my flows are welded in. U probably have done it a few times already but loosen and try again.

Well I don't have that setup, but I think alot of people do, and havn't had any problems.

I just wanted to say that you two guys have someamazing cars.

ive got the prochamber, pretty much the same thing, i just used an electric impact wrench, i went as tight as i could untill the flanges holding the bolts started bending and i was like wooooooh stop, i think i still have a leak at the headers though. thats more important than at the catback, bc whenever you turn on the heater when stopped thats what you smell, gasoline fumes... i like it, but everyone else that rides with me, not so much

3 section / 5 piece.

I'll probably tear it down and try again this weekend.

Put it alltogether butleave the bolts loose. Take ur time andmake sure everything is lined up. Gradually tighten each bolt as u would the lugs on your wheels.Then crank the hell out of um!

I got fed up with mine and had to have it realigned at a muffler shop..... Good Luck!!
