2G Downpipe for Thermal R&D catback

[tinytoh]

Hey,

For those of you using Thermal's 3" cat-back (2G)...

What downpipe/ O2 housing are you using??

Where did you get it from??

Thanks,

Eric

I plan on using a local shop's downpipe (AMS), haven't decided to either run with an o2 eliminator or not. If at all possible, I'll probably port the fluff out of the stock o2 housing.

any 2.5" DP will work but dont get a 3" because the Thermal bottle necks to fit to the stock cat. As for the o2 housing i have a ported 2G o2

I have a 3" A'pexi N-1 downpipe w/ a cat eliminator. I bought a universal Thermal RD muffler and had a local shop whip up a 3" catback.

I bought my downpipe used, and got my muffler from www.nipponpower.com

I've got an HRC Eliminator 3" Downpipe with their tubular O2 housing. Of course it didn't bolt right up to my exhaust. But that was of no concern to me as I hacked off the part of the exhaust where it necked down to meet up with the stock cat, and also put a 3" high flow cat in place (don't want to chance running a straight pipe around the streets here in cali).
