The Class KR Rear Exhaust Section (T713181R Series) is a JQR-certified, axle-back style system designed to elevate the rear aesthetics and exhaust note of your GR86 or BRZ.

Offering a choice between premium Stainless Steel or lightweight Titanium Face tailpipes, this component provides a significant visual and acoustic enhancement, connecting seamlessly to your existing center pipe while operating within certified road-legal sound limits.

Product Highlights

✅ JQR-CERTIFIED FOR DIRECT ROAD LEGALITY
This rear exhaust section carries official JQR certification (JQR10213139), ensuring full compliance with road noise regulations. It is a guaranteed legal upgrade that enhances your vehicle’s character without any compromise to on-road usability.

🔊 REFINED AND SPORTIER ACOUSTIC PROFILE
Engineered to refine and deepen the exhaust note from the axle back, delivering a more engaging and sporty sound that remains sophisticated and within legal limits:

• Nearby Exhaust Noise: 88 dB

• Idling Noise: 62 dB
  This focused upgrade improves the quality and presence of the exhaust tone behind the cabin.

🔧 AXLE-BACK DESIGN FOR SIMPLE UPGRADE
A “rear piece only” design, meaning it replaces only the muffler and tailpipe section from the axle backward. This allows for a straightforward, cost-effective upgrade that connects directly to the factory or an aftermarket center pipe.

• Simple Installation: Direct bolt-on to existing mid-section.

• Compatible with: All standard GR86 and BRZ grades (excludes BRZ Cup Car Basic and STI Sport TYPE RA).

🏁 DUAL FINISH OPTIONS WITH COMMANDING 115MM TIPS
Choose the finish that matches your style and performance goals:

• T713181RC: Features premium Titanium Face tailpipes for a distinctive blue-hued finish and reduced weight.

• T713181RP: Features high-quality polished Stainless Steel tailpipes for a classic, durable shine.
  Both options feature massive, commanding 115mm slash-cut dual tips.
