These downpipes connect the turbo to a TOG style downpipe which then connect to your catback exhaust. All flanges and piping are 304 stainless steel and are tig welded. They are all one piece with no seams. Use in conjunction with our crossover pipe and wastegate dump tube for building your own turbo setup!
Z3 - This is the 2.5 inch version (shown in picture) and supports up to 500HP.
Stattama - Now this is a T4 downpipe and is 3" in diameter. This downpipe has a wastegate flange for recirculating your wastegate outlet back into the downpipe. Because of that, this downpipe must be purchased with the matching crossover pipe because they have to be built together for proper fitment. The large diameter this downpipe will require a smaller diameter brake booster from the 2001+ Monte Carlo/Impala.
Both downpipes have V Band inlets and an O2 bung for the primary O2 in an easy to access location.
Tech support on building your own kit is not available. This piece is made to only work with our Turbo, wastegate, and crossover. We are not able to custom make any of our turbo parts to fit with other vender parts.
This piece is not compatible with C.T. or any other brand turbo kits.
