R1-Spec Catback Exhaust - Subaru WRX/STI VA [2015-2021]
R1-Spec catback exhaust system was developed for those seeking maximum performance gains. This single exit catback exhaust system reduces back pressure restriction, and offers significant weight savings. The 3 inch diameter piping and low restriction layout helps the exhaust system breath by reducing exhaust gas back pressure. Our high flow straight through muffler canister creates an aggressive tone which might wake the neighbors but fits in perfectly while at the track, The large 4.5 inch slant cut tip matches the performance nature of the system. The muffler canister is available in Full Titanium construction or Stainless steel construction. Both variants include 304 stainless steeling piping and flanges.
Designed and manufactured for the hardcore enthusiasts. Inspired and designed for the track ready Subaru WRX/STI VA.
