ISR Performance ST Series Burnt Tip Exhaust - Scion FRS, Subaru BRZ, Toyota GT86, GR86

The ISR Performance ST Series Burnt Tip Exhaust is a dual-exit dual-muffler catback exhaust for the entire Toyota 86 / Subaru BRZ platform family. Covers the original GT86, Scion FRS, Subaru BRZ, and the current Toyota GR86. 3 inch mandrel-bent stainless steel with twin 4 inch burnt blue tips for a more aggressive look and tone than the resonated single-tip GT variant.

What It Does

Catback exhaust replaces the entire exhaust system from the cat back to the tips. The ST Series uses a dual-exit dual-muffler design with twin 4 inch burnt blue tips, which gives the car a more aggressive presence and a deeper tone than the single-exit GT variant. The 3 inch mandrel-bent piping flows enough for both naturally-aspirated and forced-induction builds, including supercharger and turbo conversions that the 86/BRZ platform is popular for.

ST Series vs GT Series

ISR offers two catback styles for the 86/BRZ platform:

• ST Series (this product, IS-ST-GT86): Dual exit, dual muffler, twin 4 inch burnt blue tips. More aggressive look and louder tone.
• GT Single Series (IS-GT-GT86): Single exit, resonated mid section, single 4.5 inch polished tip. More refined tone, less drone.

Pick based on whether you want louder and more aggressive (ST) or more refined daily-driver tone (GT Single).
