PERRIN Catback Exhaust for BRZ / FR-S / 86 / GR86

Transform your ride with the PERRIN Catback Exhaust, engineered for drivers who demand style, sound, and durability.

Key Features & Benefits

• Full 304 Stainless Steel Construction
  Crafted entirely from brushed 304 stainless steel, this system offers superior corrosion resistance and a premium, polished look. 

• Enhanced Sound & Tone
  Larger 3" piping gives the exhaust deeper tone and more volume over stock. A built-in Helmholtz resonator helps eliminate drone at lower RPMs, offering a refined sound without harsh resonance.

• Striking Single Slash Cut Tip
  Designed with a 4.5" diameter slash-cut tip, this exhaust fills the bumper cutout aggressively and gives your rear end a purposeful, race-inspired aesthetic. 

• Weight & Power Gains
  Weighing in at 28.7 lbs, the system is about 6.4 lbs lighter than OEM. On a stock-tuned 2022 BRZ, PERRIN measured gains of 3–4 WHP and 3–4 ft-lbs of torque from just the rear section swap.

• Warranty & Support
  Backed by a 5-year warranty against defects in material and workmanship (some exclusions apply). 

• Quick Installation
  Estimated DIY install time is about 45 minutes.

Performance Highlights & Design Notes

• The oversized 3" piping delivers louder, richer sound than stock while maintaining flow. 

• The Helmholtz resonator addresses one of the common BRZ/FR-S/86 issues — low-RPM drone — by targeting and reducing unwanted resonance. 

• The visual styling — particularly the tip design — complements aggressive rear bumper styling and highlights the performance intent of the system.
