Upgrade Your 2020+ Toyota GR Supra with the AMS Performance MKV A90 Street Downpipe

If you're looking to enhance the performance of your 2020 and newer Toyota GR Supra, the AMS MKV A90 Street Downpipe with an EPA-verified Ultra High Flow GESI Catalytic Converter is a game changer. Designed specifically for the 3.0L engine, this downpipe not only improves power delivery but also optimizes turbo spool-up, giving you that exhilarating acceleration you crave.

Performance Benefits

The AMS downpipe features a robust 4.5" full mandrel bent design that allows exhaust gases to flow freely, minimizing back pressure and maximizing power potential. With long, gradual transitions, this downpipe ensures that exhaust gases maintain their velocity, which translates to earlier power delivery. You'll notice improved throttle response and a more aggressive exhaust note, especially under wide-open throttle conditions.

Engineering Excellence

AMS Performance is renowned for its engineering prowess, and this downpipe is no exception. Utilizing advanced CAD software, the AMS engineering team meticulously designed the inlet and outlets to ensure optimal exhaust flow. Constructed from heavy-gauge 304 stainless steel, this downpipe retains heat efficiently, enhancing performance while also reducing the risk of cracking—common in lesser products. The inclusion of threaded O2 sensor bungs allows for seamless integration with your factory O2 sensors, ensuring a hassle-free installation.
