Extreme Turbo Systems ETS 2020 Toyota Supra GR A90 MKV High Flow Cat Downpipe


SKU: N/A Category:


An ETS Pro Series Downpipe should be  the  first upgrade you purchase for your 2020 Toyota Supra, as the factory downpipe significantly  chokes  exhaust flow at the  end of the downpipe near the catback connection.   Our Pro Series upgrade turns your factory 3.15″ downpipe connection into a massive 4.00″ connection, which increases flow area by over 21%.

Do you already have an aftermarket exhaust that works with the factory downpipe?   Don’t worry, we have you covered!   We offer a Factory/Stock Replacement downpipe connection for those that want to run factory or   stock replacement aftermarket exhaust systems.

Don’t settle for a cheap downpipe that will fail down the road.    The ETS 2020 Supra Downpipe is built out of the highest quality 304 stainless steel and incorporates a TurboFlex coupling designed specifically for turbocharged applications.   Traditional flex sections will fail and/or collapse under extreme heat.
