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 recirc fabrication tube for building your own turbo setup!

Z3 - This is the 2.5" version and supports up to 500HP.

Stattama - Only available with matching crossover, found here. 

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.

Our downpipes come with a high flow catalytic converter that is 48 state legal. Our catalytic converters will not pass California or New York state emissions. Please contact customerservice@zzperformance.com if you have any questions.
