B58 Downpipe Upgrade

The VRSF Downpipe Upgrade is engineered to enhance the performance of your 2020 – 2024 Toyota Supra featuring the B58 engine. This downpipe is constructed from hand-crafted, tig-welded 4.5″ 304-grade stainless steel, ensuring durability and corrosion resistance. The design includes a CNC-machined 304-grade stainless steel flange for a smooth transition from the turbo to the mid-pipes, and features smooth radius bends to minimize turbulence and maximize flow. This upgrade is available in two configurations: a high-flow catted version with a 200-cell catalytic converter or a track-limited racing downpipe. Both options aim to reduce back pressure compared to the stock unit, resulting in improved performance metrics. When paired with a DME remap, VRSF claims gains of up to 100 wheel horsepower (whp) and 89 wheel torque (wtq) on pump gas. For those seeking maximum performance, there are also claims of up to 177 WHP & 188 WHP with specific tuning. VRSF offers a Lifetime Warranty on their downpipes, with the exception of the catted downpipe, which carries a limited two-year warranty.
