Product Details

The Two Brothers S1R full exhaust system is the modern race-line exhaust — carbon fiber sleeve, aluminum CNC-machined outlet, stamped spring-mounted inlet, and a high-temp aerospace-grade epoxy carbon construction. Dyno-tuned and track-tested for street and circuit use.

  • Full exhaust system — replaces stock header and muffler
  • High-temp aerospace-grade carbon fiber construction
  • Spiral-wound perforated core for the signature Two Brothers tone
  • Aluminum CNC-machined outlet with Teflon-coated magnesium end cap
  • Removable P1X power tip for sound tuning (where included)
  • Race / closed-course use — not all configurations are DOT/EPA-compliant in all states; check local regulations before street use
