If you want your bike to wear its exhaust as well as James Bond wears a tux, check out the Two Brothers Silver Series Exhaust. The exhaust is highlighted by a natural finished aluminum inlet and outlet and a badge design that screams Merica! Topped off with the TBR famous teflon-coated magnesium end cap gives the Silver Series Exhaust a clean and dazzling appearance.
The Two Brothers Silver Series exhaust systems are available in 6061 aluminum and aerospace grade carbon fiber. From TBR’s humble beginnings, lightweight, polished aluminum has been a staple in the TBR lineup and continues to be a popular choice for all riders. The carbon fiber sleeve of the M2 Silver Series Exhaust is made of a 33 million modulus rated carbon fiber that is impregnated with high temperature resin, under very tight tolerances. Thirty-three million modulus rated carbon fiber can be considered the Goldilocks of carbon fiber, it has strong structural properties without being overly stiff and brittle, making it just right. Inside the M2 Silver Series Exhaust is TBR’s proven spiral-wound perforated core technology that gives all Two Brothers exhaust their deep and throaty roar. The exhaust connects by way of TBR’s V.A.L.E. system and #304 stainless steel mid-pipes.

I want to get the only drawback out fo the way, since it's for the Bolt, I believe they should offer it in matt black. Carbon fiber simply does not work well with the bike. Silver draws the eye too much. Since the style of muffler clearly ends itself to cafe/retro... Just, they need black so you don't have to paint it. The Silver Series pipe is oval, though in all photos it appears much more round than it actually is, and I feel it looks way better on the bike. It's build quality is outstanding as you would expect from TBR.
Installation:
Installation was a bit tricky but not difficult, mating the midpipe to the muffler required I loosen and tighten the all mounting points more than once. The top screw closest to the bike was hard to reach and tighten properly.
Performance:
I instantly noticed an increase in pull and the throttle response is improved significantly. The pipe is the only engine mod, I did not install a controller or intake.
Sound:
In my case, this is an instant winner. If you are looking to sound like a thunderous beast rolling down the road, this is not the pipe for you. If you want to sound like a well tuned, performance V-Twin, it's a serious winner. Using the included p1 sound reducer, the pitch is a little higher than the giant stock pipe and the volume, while considerably louder, is not nearly the ear pounding sound of straight pipes.
Finally, If you just want a kick in HP and a drop in weight, or if you're building a retro or cafe style, this pipe is outstanding.
