These Mild Steel mandrel bent downpipes are designed to replace the very restrictive 300zx precats. With the smooth 2 1/2" piping and split design they allow for quicker spool up and better top end power.
The 5 bolt design is made to fit VG30 JWT 530s, 650s, 700s and HKS 2530s with wastegate separators.
** Can be upgraded to Stainless Steel for an additional $60 **
