Yea CycleSavage the noise would seem to go farther back with the open end cap but actually Supertrapp states that the open end cap is like adding 6 Discs which reduces backpressure and increases noise. If you haven't already you might want to install the closed end cap and check it out if its still a little too loud that might make it just right. ( If you do let everyone here know )
Looks good Karl, I've always wanted to see two Carbon Fiber mufflers fitted to a V Rod, with the Akro it would take an adapter from one pipe to 2 but with yours - maybe just an upward bend staggered between those two pipes and VOILA instant super cool looking and sounding system, back mount strap them to the footpeg bracket like stock - Just Sayin' - ( maybe after your drag pipe baffle install ? : )
I have 2 1/4" slip-on slash cut open pipes behind the stock head pipes. Used an old skool drag pipe trick of welding a big flat washer on the head of a 5/16" bolt and putting the bolt/washer 1 1/2" from the end of the pipe. The washer can be turned to dial in back pressure and sound level.
I have mine turned 1/3 from edge on. Takes the snap out of the exhaust note and the seat of the pants dyno says it pulls just as hard. Not to mention the pipes are Kool!
you know, whether you have a quiet or loud bike you should wear ear plugs when riding, I wish I had worn them every time from the very beginning. that wind noise is murder on your ears! one thing is for sure the revo seems to hate backpressure and the revo without (and sometimes with) a muffler is hellaciously LOUD! I had a cfr on mine until last season and im not sure if it could have been any louder but damn it sounded badass! Now that my V-rod is going to primarily a drag bike im installing an open 2 -1 race pipe, I know street use will be very limited, and if my nabors didn't already hate me im sure they will now ! lol
I ditched the SuperTrapp 4" weld on plan on my Bub 7 2-1 but with my new S.S. BMW 4" automotive carbon fiber covered resonator with 3 1/4 inch I.D. it's still a straight thru pipe but noise and higher frequencies are dampened down, with much better overall cadence - don't need to short shift it to keep the noise down, still not a purring sound like my Triumph 3 Cylinder but it's not meant to be. Every M/C engine configuration is a little different, all can be obnoxiously loud if desired but why ? Make Music not Noise.
Where does the short, slash-cut tip come from? Every Akrapovic Muscle set-up I've seen, has come with the big, clunky sportbike-type canister. The short tip looks killer!

My '13 NRS came with V&H Black Widow slip-ons when I picked it up.
They sounded OK but I hated how long they were. Ended up taking them off and selling them after finding a BNIB CFR for cheap.
The CFR makes my VROD sound deep and throaty but man is it LOUD when the throttle is cranked. Good thing I wear a FF helmet and ear plugs.
The big bonus is my wife can hear me coming blocks away and hits the garage remote for me....
