REMARK 4.5" Single Wall Axleback Exhaust

REMARK 4.5" Single Wall Axleback Exhaust - GR86 / BRZ (2022+)

Raw Boxer Sound, Lightweight Design, and Aggressive Track Styling

Wake up your ZN8/ZD8 chassis with the REMARK Single Wall Axleback. This "muffler delete" system is engineered for the enthusiast who wants an unfiltered exhaust note and a simplified, race-ready aesthetic. By removing the heavy, restrictive factory mufflers, you improve the car's power-to-weight ratio and throttle response. The 4.5-inch single-wall tips offer a thinner, sharper profile than the "double wall" versions, giving your build a classic JDM track-car appearance while perfectly filling the factory bumper cutouts.

Available Variants:

- Polished Stainless Steel (RO-TSZ8-S): Features a mirror-finished T304 stainless steel tip for a timeless, high-performance look.

- Burnt Stainless Steel (RO-TTZ8-S): Features the iconic heat-treated "burnt-blue" finish for a technical, high-end appearance that mimics titanium.

What’s Included in the Box:

- Axleback Sections: Left and Right muffler-delete exit pipes.

- 4.5-Inch Single Wall Tips: (2) Oversized slant-cut tips with laser-engraved REMARK logos.

- Installation Hardware: Includes all required high-quality gaskets and zinc-plated bolts.

- OEM Hanger Compatibility: Designed to slide directly into your factory rubber exhaust hangers.

The REMARK Advantage

- Instant Bolt-On Power: This is a true "plug-and-play" modification. With basic hand tools, you can transform your car’s sound and look in under 30 minutes.

- Significant Weight Savings: This system removes roughly 15 lbs from the very end of the vehicle, which helps sharpen the car's handling and weight distribution.

- Aggressive Acoustic Profile: Expect a deep, authoritative rumble at idle and a fierce, mechanical scream as you climb toward the redline. It is significantly louder than the stock system.

- Full 2.5-Inch Mandrel Bends: Every bend is mandrel-formed to ensure a constant diameter, maximizing exhaust flow and reducing the backpressure created by baffled factory mufflers.

- Hand-Finished TIG Welds: Precision welding ensures a leak-free seal and structural integrity that holds up to the heat and vibration of spirited driving.

Precision Tip: Because this system deletes the mufflers entirely, your "cold starts" will be very loud. To keep those 4.5-inch tips perfectly centered and prevent them from swaying during hard cornering, we highly recommend upgrading to Whiteline Stiffened Exhaust Hangers. This ensures your exhaust stays put and looks as sharp as it sounds.
