Milltek Sport Cat-Back Exhaust - 2020-2026 Toyota GR Supra 3.0 A90

This Milltek Sport cat-back exhaust fits the 2020-2026 Toyota GR Supra (A90) with the 3.0 liter B58 turbocharged inline-six, with either the automatic or the manual gearbox. The Supra already has one of the best-sounding six-cylinder engines on sale, and a Milltek system lets more of that smooth, rising howl through while cutting weight from the rear of the car. Milltek offers three versions for the Supra: a resonated system for a deeper, refined tone, a non-resonated race rear silencer with non-valved outlet pipes for a louder sound at all times, and a valved race system that keeps the factory exhaust valves so you can still pick a quiet or loud mode from the drive settings. Every system is built for this exact chassis, so it follows the factory routing, hangs from the stock mounts and keeps the ground clearance of the original exhaust. Each one is made from T304L stainless steel with mandrel-bent 70 mm (2.76 in) tubing, so the pipe keeps its full size through each bend and resists corrosion for years. It bolts on with the factory hangers and clamps, with no cutting or welding needed.

How to Choose

Start with the Sound. Non-Resonated, Non-Valved (Louder) uses a Milltek race rear silencer with non-valved outlet pipes, so the exhaust stays open and loud at every speed. Valved Race (Louder, Switchable) also uses the race rear silencer but keeps the factory exhaust valves, so it is loud in Sport mode and calmer when the valves close. Resonated (Quieter) keeps a resonator for a deeper, more refined tone with less drone on the highway, and it is the quietest of the three.

Then pick an Exhaust Tip Finish. All five use twin 115 mm tips: Polished GT-115 (bright polished stainless, round GT tips), Cerakote Black GT-115 (a black Cerakote ceramic coating), Brushed Titanium GT-115 (brushed titanium), Burnt Titanium GT-115 (heat-blued burnt titanium) and Carbon Fiber Jet-115 (oval Jet tips with carbon fiber trims). The finish changes the look only, not the sound.

Planning more power? Milltek also makes catted and catless downpipes and a resonator bypass for the GR Supra 3.0, which bolt up to these systems or to the factory cat-back.
