BA-BF XR6 TURBO SEDAN 2003-2007 X-FORCE 3.5" CAT-BACK SYSTEM ONLY BOLT TO XFORCE DUMP & CAT KIT

XForce 3.5" Cat-Back System — BA/BF XR6 Turbo Sedan

The rear half of the XForce turbo-back package. Full 3.5" bore in raw 409 stainless with a straight-through sports muffler, sized to match the dump pipe and cat kit rather than fight it — so the whole system flows as one piece instead of pinching at the joins.

Expect faster spool and a harder, deeper note than the factory system, which on the turbo six is as much about what you remove as what you add.

Specifications

Important: this is the cat-back section only — it bolts to the XForce 3.5" cat and dump pipe kit, not to the factory cat. The twin tip outlet requires welding.
