RRM axleback exhaust discussion thread
my mac played it great rock
I cant wait, got my USPS shipping info and my exhaust left on friday at 7:06 pm. So I am thinking sometime this week and have it by the weekend. Perfect time to burn a tank of gas!

SO SO sorry if this has been discussed already, but I was curious about the RRM exhaust being an axle-back exhaust, instead of cat-back? Does anyone (rock?) know if there would be benefit from getting the local muff shop to fab up a larger diameter cat-axle pipe, and then use RRM exhaust? or would the gains be so little I'd waste my money? Thanks all.

There's a catalytic converter directly in front of the exhaust flange. If you paid attention, you'd know that the RRM exhaust is BOTH a catback and an axleback.
It's a catback because the piping starts right after the cat.
It's an axleback because the piping starts right around the axle.
Does that make it clear enough?
Yes. doing a catback would be futile and not make more power. car is very senssitive to backpressure. We tried many combos that flowed more and it lost power. The axelback we made seems to be the perfect combo of top end and low end.

Hey Rock, what is the typical time for my shipment to come? I ordered it from you guys on the 3rd. It was shipped on the 7th, came to canada (which i hope is somewhere in bc otherwise it is going to take forever) on the 9th and now it seems to have stopped/disappeared?

sorry about that
speak of the devil I just got an email from USPS saying it cleared customs today. 9 days to clear customs, nice!
On another note, I was wondering if you guys know the weight saved from the new exhaust to the old one? not just the enhancment of flow but this also means my car will shed a few pounds. The stock one just looks like a bloated beast

To be honest it was a little tougher than i thought, not technically but the damned bushing only come off easily in a certain order. And I figured that out the hard way. ThenI had an idea where to put each new bushing but I would go underneith and try to eye ball it. But after an hour of hitting my head I finally got it.
It sounds great, under light load you barley hear hear it if at all (no worse than stock anyways) but when you open here up you def hear it.
I know that it isn't properly in the bumper cutout but I am going to try this afternoon and get it fixed. Thinking I will undo it at the axle, align it and then bolt it back up


THANKS ROCK!
