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.DOWNPIPE DESIGN FEATURESCNC 304 Stainless Steel Turbo Mating Flange4.5" to 4.0" or 4.5" to 3.15" Design (see the picture below)Full Stainless Steel ConstructionTurboFlex coupling featuring an internal stainless steel interlock liner that facilitates smooth flow of high temperature exhaust gases.Reinforced mounting bracket designed to last the life of your vehicleFully Tig Welded In HouseDirect Bolt On Design2.5lbs lighter than factory downpipe (race downpipe) DOWNPIPE TYPEStreet DownpipeDesigned with a GESI High Flow Cat for street use.Race/Off-Road DownpipeDesigned with a straight through designed for Off-Road and/or Track use only.
