Category: Street Series Exhaust System

This carbon fiber and titanium masterpiece is the cherry-on-top for the ultimate build. We haven't built this beauty in a few years and is no longer included in any current exhaust system so we decided to make this mini gem available for our Builders Series. Expensive -yes, but you would have the sickest system at the show with this bad boy. Sound, looks, and performance! Grab one before they go extinct again.


  • Carbon fiber and titanium construction
  • Weight just 2.5 pounds!!!
  • RS-3 Elliptical shape
  • Sound is one of a kind

Proudly designed and made in the USA!

Riley C. ★★★★★

The carbon fiber weave is flawless, and it bolted right up in less than an hour. I've been after that deep, aggressive tone for years, and this kit finally delivers without being obnoxiously loud.

Owen ★★★★★

Finally got to hear this thing in person after drooling over the build photos — the carbon fiber finish is flawless and the titanium tip gives it a deep, aggressive note that's totally worth the wait.

Amelia ★★★★★

I’ve been hunting for a lightweight, quality mini bike muffler for ages and this titanium setup totally delivers. The carbon fiber wrap actually feels solid, not flimsy, and the fit was spot-on with no extra brackets needed. Took about 30 minutes to install and the tone is deep but not obnoxious.
