PA Valved Titanium Catback Exhaust for MK5 Supra 3.0T (A90 / A91)

Unlock the true voice and performance potential of your Toyota GR Supra’s B58 3.0T with this full titanium valved cat-back exhaust system. Engineered specifically for the MK5 (A90/A91) platform, it delivers huge weight savings, unrestricted flow, and on-demand sound control that transforms the car from refined daily driver to raw, high-revving machine at the push of a button.

Crafted entirely from high-grade titanium, the system is TIG-welded with precision for strength, clean aesthetics, and long-term durability under extreme heat and vibration. Mandrel-bent tubing throughout minimizes turbulence and maximizes exhaust gas velocity. Pipe diameters are optimized for high-flow performance. This system removes roughly 30 lbs compared to the heavy factory exhaust—improving overall vehicle balance, throttle response, and handling dynamics.

The complete assembly—including piping, muffler, valve body, and hardware—is fabricated from titanium to keep mass low and thermal consistency high. Mandrel-bent tubing and carefully optimized wall thickness promote smooth gas flow, reduce turbulence, and help the system withstand sustained heat without adding unnecessary bulk. Interior and exterior surfaces are finished to minimize flow restrictions and give the exhaust a clean, premium appearance under the car.

A dual-mode valve system puts the driver in control. In closed mode the exhaust gases travel through a tuned multi-chamber muffler for a restrained, neighbor-friendly tone ideal for daily driving and long highway runs. Open the valves and the system switches to a freer-flowing path that produces a sharp, exotic titanium soundtrack—clear turbo spool, aggressive mid-range pull, and a crisp top-end note that stands apart from typical stainless systems.

The valve works with the factory sport button on supported models and can be paired with an optional dedicated controller where preferred. High-flow routing and chassis-specific muffler design keep backpressure low, support power upgrades, and maintain drivability across the rev range. Installation is a direct bolt-on using factory mounting points, fully reversible, and engineered to sit cleanly beneath the rear diffuser with properly proportioned tips that fill the bumper openings without looking oversized.

The result is a lightweight, tunable exhaust that feels refined when you want it quiet and properly alive when you open it up—built specifically for the A90/A91 Supra rather than adapted from another platform.
