Two Brothers Tarmac Exhaust System Honda Grom

The Two Brothers Tarmac Exhaust System features an unmistakable trapezoidal shape muffler that stands out from the rest of the TBR exhaust line. This unique shape not only increases lean angle clearance but also maintains optimal internal exhaust volume and performance. The muffler is constructed with a CNC-machined stainless inlet for a seamless fit, billet CNC outlet and rivet bands with larger 5/32” rivets for added strength and durability. So as to not compromise the great lines of the TBR Tarmac Exhaust, it features a strapless integrated machined aluminum exhaust hanger. TBR’s signature spiral-wound perforated core combined with the removable T-Tip insert ensures a muscular and full-throated exhaust note.

The carbon fiber sleeve of the Tarmac Exhaust is made of a 33 million modulus rated carbon fiber that is impregnated with high temperature resin. The carbon fiber is then cured under vacuum with over a 100 psi to remove any air that is trapped in the carbon fiber laminate. TBR exclusively uses thirty-three million modulus rated carbon fiber for the Tarmac Exhaust because of its strong yet lightweight properties.

All exhaust pipes of the Tarmac Exhaust Systems start life as .035" thin wall #304 stainless steel tubing. #304 stainless steel, a lightweight austenitic chromium-nickel stainless steel which has low thermal conductivity properties and is corrosion resistant, even in the harshest environments. TBR then takes this versatile alloy and infuses it with their stepped exhaust technology. The stepped header system forces the exhaust gases to travel through incrementally larger diameter exhaust pipes on its way to the muffler. This design creates a vacuum effect that forces hot exhaust gases out, allowing your engine to breath better while simultaneously increasing horsepower, torque and throttle response.

Features:

  • Teflon coated magnesium end-cap
  • Stainless steel springs
  • Stamped spring-fit inlet
  • Optional anodized bolts kits available (sold separately)
  • Made in USA
