REMARK 4.5" Double Wall Axleback Exhaust

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

Maximum Sound, Minimum Weight, and Premium Double-Wall Styling

Give your ZN8/ZD8 chassis a voice with the REMARK Double Wall Axleback. This system is engineered for the enthusiast who wants a loud, mechanical, and unfiltered exhaust note without the cost or complexity of a full catback. By eliminating the bulky OEM mufflers, you shed roughly 15 lbs from the very rear of the car, which helps with weight distribution and throttle response. These specific "Double Wall" variants feature a thicker, rolled tip design that looks more substantial and high-end than standard single-wall tips, perfectly matching the aggressive lines of the 2022+ bodywork.

Available Variants:

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

- Burnt Stainless Steel (RO-TTZ8-D): Features the signature REMARK heat-treated "burnt-blue" finish on the tips for a technical, JDM-inspired aesthetic.

What’s Included in the Box:

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

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

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

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

The REMARK Advantage

- Direct Bolt-On Installation: This is a "driveway-friendly" mod. It requires no cutting or welding and can typically be installed in under 30 minutes using basic hand tools.

- Aggressive Sound Profile: This system provides a deep, growling idle and a fierce scream at high RPM. It is significantly louder than stock, making it perfect for those who want their car to be noticed.

- Full 2.5-Inch Mandrel Bends: 16-gauge T304 stainless steel piping ensures that exhaust gases exit as quickly as possible, reducing backpressure compared to the baffled factory mufflers.

- Premium Tip Construction: The "Double Wall" design provides a more finished, "OEM+" look. The dual layers help prevent heat discoloration on the outer edge of the tip while providing a heavy-duty feel.

- Precision TIG Welds: Every joint is hand-welded to ensure structural integrity and a beautiful, leak-free finish that stands up to the elements.

Precision Tip: Because this is a muffler-delete system, it is loud. You will experience a very authoritative "cold start" in the mornings. If you eventually find that the sound is too raw, you can always pair this later with the REMARK Resonated Midpipe to smooth out the tone and reduce interior resonance without losing the aggressive 4.5-inch look.
