Finally, installing my headers.
I've had my headers in the garage for a few months now, and I'm finally going to install them this next weekend, but I have a few questions, they may be stupid but here goes.
Do I need a ORY pipe or a catted mid-pipe or can I have the exhaust shop just fab. where the exhaust pipes slip on the collector?
I would like to keep my cats on, will these headers interfere with that, or should I just get catted mid-pipes?
They are pacesetter ceramic coated long tubes (pt#72C2258) from gravana tuning.com, with the O2 sensor bung, will I be able to pass emissions with these as long as I keep the cats?
Thanks guys, I'm fairly new to the LSX set-ups, and I'm not real worried about emissions but it would be nice to pass if I need to.2006 impulse blue G.T.O

Yes, you'll need mids. Gravana didnt offer mids with the headers?

Yeah most headers come with mid-pipes and you get to choose off-road or w/ cats.

well these headers didn't come with the mids, so I'll buy them, the only pacesetter mids I can find are OR no catted, do you know how far back the cat is from where the collector will be?

Most mid pipes with cats that I've seen have the cats almost directly after the collectors
