If you're seeking to build a turbo 3800 and make more than 500whp, our Stattama crossover and downpipe combo is a must. We offer our full Stattama turbo kit here. These pieces must be purchased together as they are fabricated as one matching unit. 

Stattama stainless crossover and downpipe - This is intended for builds of 500+whp.  This crossover has a T4 flange and it is designed for use with our T67 turbo and 3" downpipe. It has a wastegate perch for our TiAL 38mm gate and a T4 flange.

The downpipe is is 3" in diameter, which will need to be mated to a TOG style bolt in downpipe to connect to your catback. 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. 

Downpipe has V Band inlets and an O2 bung for the primary O2 in an easy to access location.

Product note: Due to fitment issues due to the large diameter or the downpipe, there will be indentations in the pipe. These indentations are intentional and needed for proper fitment. Any concerns, please email customerservice@zzperformance.com. 

Tech support on building your own kit is not available. This piece is made to only work with our Turbo, wastegate, and downpipe. We are not able to custom make any of our turbo parts to fit with other vender parts.
