Tailgunner Rotary Cannon Exhaust | Topgunner exhaust
Is what I put on mine. I wanted to go cheap, but look good and sound good. I also couldnt find a "cat eliminator" for the 2012, only up to the 2008s.
I went to NAPA, ordered 2 45deg elbows in 2" (about $20 each) cut them at the proper angle to get the offset needed, then rewelded them together.
Ordered the billet aluminium adapter from Tailgunner to go from 2" down to the factory outlet size on the factory header. (about $30)
I got the topgunner version that is about 21" long, and took the baffles out. It has a great growl going down the road, and it barks pretty well. They have a shorter version 15" or so, but the 21" version falls out pretty close to the stock holes in the stock rear muffler support, and doesnt stick out past the rear tire. Any shorter than the 21" you would need to get creative with the location, and may have a bit of a heat issue if you carry passangers. (about $450)
I also liked that by doing so I was able to mount a tool bag under the chassis where the Cat was, and after removing the Left side muffler mount, a simple piece of strait stock made a good platform for a fork bag, and side mount license plate holder. (pic 2)
NOTE: I put this free breathing system on, then had to take my bike to the dealer 105mi away to have them try the triumph TOR tune. It had a LOT of decel pop and got hot enough that it discolored the powdercoat. Additionally I have the pipe fiberglass wrapped because I put forward controls on and like to stretch out, so it got hotter than it should have, and stayed hotter because of the wrap. No big deal, I put some decals on the muffler, then repainted it with 2000 deg header paint, so now it has some "ghost" graphics in it. (pic 3 is before it was repainted, and when the "original" attempt I made at the "non welded" pipe that was made of adapters from napa and JB welded to seal, then wrapped in fiberglass....it failed. The hose clamp was a "field save" and hadnt been fixed yet. I promise if you look, there is a bike and a muffler on the bike)
I had about $550 in the whole set up including the Triumph tune dropped in. Im very happy with it, and after the next check dropped the green on a power commander V with auto tune, and all problems solved.
The last thing to weigh in on here is to keep in mind the R3 is an in line 3....its not a V twin....there is ALWAYS going to be noise and air in the exhaust, no matter what you do. You are never going to get that distince "thud thud thud thud" you get from the alternating of a V twin with dual pipes. All sound and all air is shared by the header pipe, and no matter what you put on the end, it is only going to change so much from that header sound. Unless someone decides to isolate each exhaust port (which could/would be cool to see) its more about what you like the look of, and how well that can be tuned to your machine. At least thats my opinion.
