RRE down pipe- Cat Back options??

[Chucker88]

I just got a used rre cat eliminator down pipe, and have been looking at cat back systems. Kinda interested in the megan cat back and was wondering if the flanges of the down pipe and cat back would mate.

And also if you have this down pipe, what exhaust did you get??

The RRE downpipe should be a typical 3" 2 bolt flange, so any system with that kinda flange will bolt right up (which should be most 3" systems). I use to run an Apexi N1 system with my RRE DP but mnow I run a custom 3" system (which bolts right up to the RRE DP with the 3" 2 bolt flanges I got from Vibrant).

With my Thermal in one hand and the RRE cat-delete DP the two would not bolt up. With the Thermals there is a bottleneck at the beginning of the piping, so it can mate up to the OEM catalytic converter. Since the cat was sitting up in the attic, this did not apply to my situation. So I had to wait a couple weeks before I could get the chance to take it to a local trusted shop. They cut and welded on a new extension.

Funny thing is, I never got pulled over for those two weeks I drove around with an open DP. The day after the Thermal was bolted on, I got stopped. And then a week after that too.

BTW, if you would like to see some pix, just ask.

haha that's just unlucky. Still not sure which one i'm gonna go with, but hopefully will soon! Price is kinda making the decision right now...
