Perrin [22-23 BRZ, 22-23 GR8] Axle Back Exhaust SS - Single Side Exit w/Helmholtz Chamber | PSP-EXT-368BR
Our resonated system is designed to have a mellow, pleasing rumble at lower RPMs and light throttle. When driving vigorously, the system transitions into an aggressive tone that every sporty car needs.
NO DRONE ZONE
The PERRIN exhaust features a frequency-reducing Helmholtz resonator to combat the naturally occurring resonance the BRZ exhaust produces. This unique, engineered chamber, reduces the low RPM droning and booming without adding any restriction to exhaust gas flow.
SLASH CUT TIPS
The PERRIN Axel Back Exhaust features a single oversized 4.5" slash cut exhaust tip that fills the bumper cutout and adds a purposeful, race car look.
CONSTRUCTION
PERRIN exhaust systems are made entirely of 304 stainless steel. Other manufacturers may use cheaper 409 stainless steel which will rust and corrode over time. Our brushed 304 stainless steel has the best corrosion resistance and appearance after use.
POWER
This test was done on a 2022 BRZ running a stock ECU tune. After swapping out the rear exhaust section, we put the car back on the dyno and found an additional 3-4 WHP and 3-4 ft-lbs. of torque.
FINISH
The PERRIN Exhaust systems come with a brushed stainless steel finish featuring TIG welding for precise, clean welds.

FAQs
Please read our FAQs page to find out more.
Are OEM products more expensive than aftermarket alternatives?
OEM products might have a higher upfront cost compared to aftermarket parts, but their superior quality and durability often make them a more cost-effective choice over time. Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.
Can I purchase OEM parts online or do I need to visit a dealership?
You don’t need to visit a dealership to get OEM parts. You can conveniently purchase genuine OEM components from authorized distributors and reputable online retailers like Turbo Tech Performance. Our online store provides a wide selection of high-quality parts delivered straight to your door.
Are parts from brands like Mopar, ACDelco, and Motorcraft interchangeable between different vehicle brands?
No, parts from Mopar, ACDelco, and Motorcraft are typically designed for specific vehicle brands. It’s crucial to ensure compatibility with your vehicle’s make and model by checking part numbers and consulting with a knowledgeable expert.
Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
Do OEM parts come with a warranty?
Yes, many OEM auto parts come with a manufacturer’s warranty that covers defects or issues. Be sure to check the warranty details for each part at the time of purchase, and keep your receipt for any potential warranty claims.
