ETS 4.5-3.15" High Flow GESI Downpipe For 20-21 Toyota Supra
An ETS Pro Series Downpipe should be the first upgrade you purchase for your 20-21 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%.
Don't settle for a cheap downpipe that will fail down the road. The ETS 20-21 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.
