Remark RK-C4063T-04T Sports Touring Quad Cat-Back Exhaust Burnt SS GR86/BRZ/86

Vehicle Fitment

• 2022-2025 Toyota GR86 (ZN8; FA24; All Trims)
• 2022-2025 Subaru BRZ (ZD8; FA24; All Trims)
• 2013-2021 Toyota 86 (ZN6; FA20; All Trims)
• 2013-2021 Scion FR-S (ZN6; FA20; All Trims)
• 2013-2021 Subaru BRZ (ZC6; FA20; All Trims)

Fitment Notes

• This is a 3-piece bolt-on cat-back exhaust, covering from the midpipe flange (factory downpipe/catalytic converter connection) rearward through the dual muffler canisters and quad exit tips. It is a direct replacement for the factory cat-back section.
• Slight alignment adjustment is required during installation, particularly on 2013-2021 models. Ensure adequate spacing between the exhaust tips and the rear bumper cutout before tightening all mounting points. The exhaust hangers are welded to OEM hanger locations, enabling direct fitment, but tip positioning relative to the bumper requires attention during the installation process.
• This is the burnt stainless steel tip variant (-04T). The same system with polished stainless steel tips is available as RK-C4063T-04. Both share the same piping, muffler design, fitment, and performance characteristics; the tip finish is the only difference.
• The system fits both the first-generation ZC6/ZN6 FA20-equipped platform (2013-2021) and the second-generation ZD8/ZN8 FA24-equipped platform (2022+). The cat-back fitment is consistent across both generations as both share the same exhaust routing geometry from the midpipe rearward.

Features

• Quad-exit design with burnt stainless steel tips - four 3-inch single-wall burnt stainless steel tips exit the rear bumper in a 2+2 configuration (two per side), providing a visually aggressive quad-tip appearance that fills the rear bumper cutouts of the GR86/BRZ more completely than the stock dual-tip layout; the burnt stainless finish produces an iridescent blue-gold heat-discoloration effect that is a signature aesthetic in the Japanese performance exhaust market, adding visual distinction at the rear of the car
• Two Remark proprietary muffler canisters - unlike simpler cat-back designs that use a single muffler, the Sports Touring uses two dedicated muffler canisters on the left and right sides; each side feeds its respective pair of 3" tips through its own muffler; this layout allows Remark to tune each side's sound character individually and provides the mechanical basis for the quad-tip visual arrangement; the proprietary canister design is engineered for the specific acoustic profile Remark targets for the Sports Touring - deeper and more complex than a straight-through design, with enough attenuation to remain usable for daily driving
• 2.5-inch mandrel-bent piping - the 2.5" pipe diameter provides increased flow cross-section compared to the factory exhaust on both the FA20 and FA24 platforms; mandrel bending preserves the full 2.5" internal diameter through each bend rather than deforming the pipe wall, maintaining consistent flow velocity through all transitions in the system layout
• 16-gauge T304 stainless steel construction throughout - all piping, hangers, and muffler canisters are fabricated from 16-gauge T304 stainless steel, providing a robust wall thickness that resists the thermal cycling fatigue and surface corrosion that undercarriage exhaust components are subjected to over years of service; T304 stainless maintains its structural integrity and appearance without the internal rust perforation that is the primary failure mode of conventional aluminized steel or carbon steel exhaust components
• Hand TIG welded - all joints, flanges, muffler canister attachments, and tip connections are hand-welded using the TIG process, producing clean, precise, fully sealed welds that resist exhaust leaks and provide a high-quality surface finish; TIG welding's superior precision and penetration compared to MIG welding results in welds that remain leak-free through extended thermal cycling
• OEM hanger locations - the exhaust hangers are welded directly to the same mounting positions as the factory exhaust hangers; this enables the system to install using the factory rubber isolators and mounting hardware without requiring bracket fabrication or modification to the chassis
• Race-inspired sports touring exhaust note - the Sports Touring designation identifies Remark's muffled cat-back configuration for this platform, producing a deeper, more aggressive sound than stock that adds character to the GR86/BRZ driving experience at all RPM ranges; the dual proprietary muffler design maintains enough attenuation to be appropriate for daily driving while delivering a clear improvement over the subdued factory exhaust note
• Weight reduction over factory - replacing the factory mufflers and associated piping with the Remark system reduces the overall exhaust system weight, providing a minor improvement in the GR86/BRZ's already favorable power-to-weight ratio

Product Description

The Remark RK-C4063T-04T is the Sports Touring Quad-Exit Cat-Back Exhaust with burnt stainless steel tips for the Toyota GR86, Subaru BRZ, Toyota 86, and Scion FR-S - covering both the first-generation FA20 platform (2013-2021) and the second-generation FA24 platform (2022+). The quad-tip layout delivers one of the most visually distinctive rear appearances available for these platforms, with four 3-inch single-wall burnt stainless tips exiting in a 2+2 configuration that fills both sides of the rear bumper with the iridescent heat-treated stainless finish characteristic of Japanese performance exhaust design.

The system is built around two Remark proprietary muffler canisters - one per side - each feeding a pair of 3" tips. This dual-muffler architecture enables independent tuning of each side's acoustic output and provides the mechanical layout required to route and terminate the quad exit tips cleanly within the stock bumper geometry. The 2.5" mandrel-bent T304 stainless piping, 16-gauge wall thickness, and full hand TIG welding provide the material quality and structural integrity that Remark builds across their product line. Exhaust hangers are welded to OEM mounting locations, enabling direct bolt-on installation with factory rubber isolators. A slight tip alignment adjustment is required during installation to achieve correct positioning relative to the rear bumper cutout - confirm bumper clearance before final tightening.

The polished stainless tip variant (RK-C4063T-04) is also available for owners who prefer a bright, unburnt tip finish. Both variants share the same piping, muffler design, and fitment.
