REMARK R1 Spec Single-Exit Catback Exhaust

REMARK R1-Spec Single-Exit Catback Exhaust - GR86 / BRZ (2022+)

Ultra-Lightweight Design & Aggressive Track-Ready Sound

Transform your driving experience with the REMARK R1-Spec Single-Exit Catback. This system is engineered specifically for the 2nd Generation ZN8/ZD8 chassis, prioritizing maximum weight reduction and optimal exhaust flow. While most aftermarket exhausts stick to a dual-exit look, the R1-Spec moves to a large single 4.5 inch exit to reduce the number of bends and eliminate the weight of a second muffler. The result is a crisp, raw, and un-muffled boxer tone that is designed to be heard. Available in two finishes to match your build’s aesthetic, this is the definitive choice for enthusiasts seeking a race-inspired setup

Available Variants:

- Stainless Steel Edition (RK-C1063T-04): Features a full T304 stainless steel construction for the piping, muffler, and tip for a classic, high-polish look.

- Titanium Tip Edition (RK-C1063T-04T): Features T304 stainless steel piping paired with a signature burnt-titanium muffler and tip for an exotic, high-end appearance.

What’s Included in the Box:

- 3-Piece Catback System: Includes the mid-pipe, axle-back section, and tip.

- 4.5 Inch Slant-Cut Tip: Features a laser-engraved REMARK logo.

- Installation Hardware: Includes all necessary gaskets and high-quality bolts.

- Removable Silencer: Specifically designed to drop decibel levels for early morning starts or long highway drives.

The REMARK Advantage

- Massive Weight Savings: By switching to a single-exit design, this system is significantly lighter than the factory dual exhaust (the stainless version weighs in at only 18.2 lbs), improving the car’s power-to-weight ratio and handling balance.

- Full 2.5 Inch Mandrel-Bent Piping: Every inch of the T304 stainless steel piping is mandrel-bent to maintain a consistent diameter, eliminating the turbulence and backpressure caused by factory "crush" bends.

- High-Flow R1-Spec Muffler: The specialized straight-through muffler design is tuned to deliver a deep, mechanical tone at idle that transitions into a fierce, high-frequency scream at redline.

- Piping-to-Tip Optimization: The 4.5 inch slant-cut tip is sized to perfectly fill the factory bumper cutout without looking undersized or "sunken."

- TIG-Welded Precision: Hand-crafted TIG welding throughout ensures maximum structural integrity and a beautiful "rainbow" finish on the joints.

Precision Tip: The R1-Spec is the loudest exhaust in the REMARK catalog. On a cold start, it registers at approximately 71dB (vs. 57dB stock). If you’re building a dedicated track car or a weekend canyon car, this is the one. If you use your car for long daily commutes, we recommend keeping the included bolt-in silencer in your glovebox for those days when you want to turn the volume down just a notch.
