ISR Performance Single GT Exhaust - Toyota GR86 / FRS / BRZ

The ISR Performance Single GT Exhaust is a catback exhaust system for the entire Toyota 86 / Subaru BRZ platform family, covering the original GT86, Scion FRS, Subaru BRZ, and the current Toyota GR86. Mandrel-bent stainless steel with a resonated mid section, single 3-inch piping, and a polished 4.5-inch muffler tip.

What It Does

Catback exhaust replaces the entire exhaust system from the cat back to the tip. The 3-inch mandrel-bent piping maintains a consistent inside diameter through every bend, which keeps exhaust velocity up on the FA20 or FA24 boxer engines. The resonated mid section gives the system a deeper, more refined tone with reduced highway drone, and the system is noticeably lighter than the factory exhaust.

Works equally well for naturally aspirated and forced induction builds, which matters since the 86/BRZ platform is one of the most popular candidates for supercharger and turbo conversions.
