The Toyota GR Supra A90 3.0 L6 exhaust in detail.
The GR Supra A90 3.0 is built around the B58, a BMW-sourced 3.0-litre inline-six boosted by a twin-scroll turbo: 340 hp and 500 Nm, torque available very early and the natural smoothness of an inline-six layout. It is one of the most admired engines in its class, and one of the most sought after for tuning.
Its voice is round and silky, then gains bite as the revs rise; the factory exhaust, which weighs 16.68 kg on its own, filters it and adds weight right at the back. With the valves open, the valved Rog cat-back lets the B58 express itself: an assertive start-up, a hoarse and continuous climb, more present downshifts. With the valves closed, the Supra returns to a calmer sound for daily journeys.
The page is for the 2020 to 2026 Supra A90 3.0; the 2.0 B48 has its own, and your VIN is checked before manufacturing. Under the Supra, installation takes about two hours, without welding, and the factory valves, if present, keep their control; failing that, the Rog remote decides.
The “Manifold” option on the page sells the B58’s downpipe, which carries the catalytic converter after the turbo. With the factory map, it simply changes the sound; remapped, the B58 reaches the 450 hp and 650 Nm published for Stage 2, headroom this engine owes to its reputation as a solid base. The six-cylinder keeps its emissions control with the 200-cell downpipe, the solution for Supras driven on the road; the 100-cell will be accepted or not depending on the car and the rules in your country, and the decat is reserved for track use. The black round tips cap a system in 304 stainless steel or in titanium, around 40% lighter.

Questions about the Toyota GR Supra A90 3.0 L6 exhaust.
Do a GR Supra A90 3.0 L6 and a 2.0 share the same Rog exhaust?
They take different parts: the 2.0 B48 is covered on its own page, this one following the 3.0 B58 from 2020 to 2026, with a VIN check before manufacturing.
Is a Stage 2 map essential to enjoy the equipped GR Supra A90 3.0?
No, the cat-back works very well with the original engine management; only with the downpipe does an ECU remap at an approved tuner exploit the B58’s well-known headroom, up to the published 450 hp and 650 Nm.
Vehicle inspection: what to plan for on an equipped GR Supra A90 3.0?
Closed valves and an original or 200-cell downpipe, for a calmer voice and an active catalytic converter. The 100-cell will be judged according to the car and your country, and the decat version is reserved for the track.
How much does the GR Supra A90 3.0’s factory system weigh?
Our data puts it at 16.68 kg, right at the back of the car. The Rog cat-back replaces it, in 304 stainless steel or titanium, the latter around 40% lighter than stainless steel for the same design.
Toyota GR Supra A90 3.0 L6: Does a valved exhaust system drone?
No. With the valves closed, the gases flow through the whole rear silencer and the cabin stays calm at a steady speed. Our Rog exhausts are designed to avoid drone. Learn more: Why our systems stay calm on the motorway.
Toyota GR Supra A90 3.0 L6: straight pipe or resonator?
On this model, two characters at the same price: the straight pipe for the raw sound of your engine, unfiltered, or the resonator for a rounder and slightly softer voice. Either way, the exhaust stays fully sporty. Learn more: Exhaust resonator: what does it do? Straight pipe or resonator, which sound to choose.
