just so you know, if you were thinking about getting two rpi mufflers to do a quad exhaust...you might not be able to fit the muffler on the right side due to clearance issues.
if you've ever looked under the vehicle the entire right side is blocked off by the battery box. There is no room to fit the muffler in that location. IMO you should try getting the
single side exhaust and while you are installing it, you'll see what I mean by clearance issues.

good luck!@

I wish I could get my power back but unfortunately it would not be possible since I got the M5 rear unless I put on the mtech rear. Is it possible if I can just get 1 rpi dual sided muffler place it where the resonator used to be, and just straight pipe it to the tips?

It is possible to fit two Rpi mufflers just the passenger muffler would have to sit vertically so it wouldn't conflict with the spare tire housing and the battery box. Plus, I don't think it is worth it to buy two Rpi mufflers being that it will cost $1800 plus labor just to install. I guess I'll just have to straight pipe it

it's possible but you have to cut the tips off and alter the original design. Which will possibly result in a loss of power! but since you've got the m5 bumper, you have no other choice. i say GO FOR IT

Nope...You could always hang a dummy pipe if you wanted...Wouldn't do anything, just be for looks...

Thanks for the tip man, yea I can give this a shot but I am afraid something could go wrong in the process, I am willing to do a test for RPi (dyno before w/magnaflow and after w/ RPi)if they can give me a deal for two mufflers without the exhaust tips

tiangco.a

so is that rpi exhaust a quad exhaust set up as well?
Id be interested in a dyno with just a dual magnaflow

I can actually do a pipe interconnecting the rpi muffler which in turn is routed to the passenger side, reminiscent of the hamann and remus quad exhaust set-up, but I would rather keep the true dual exhaust custom magnaflow set-up I have now

At the moment RPi ONLY makes a single sided exhaust...There is talk of making a dual exhaust in the future...If I were you, I would just wait...Its not worth hacking up two good mufflers to do this...Also there is no guarantee that your car will make power once you try this...You may end up wasting alot of $$$$ with no results...A single side exhaust for our cars has DUAL tips...A dual sided exhaust has quad tips...There is no quad exhaust....Its a dual exhaust...
