XForce 4" Dump Pipe & 3.5" Turbo-Back System — BA/BF XR6 Turbo
The complete job, from the turbo flange back. A 4" cast-top dump pipe clears the biggest restriction on the car, feeding a high-flow 3.5" metallic cat and a full 3.5" cat-back behind it.
Doing all three at once is the point — a dump pipe into a stock cat, or a big cat-back behind a factory dump, leaves most of the gain on the table. Matched end to end, the turbo spools noticeably harder and holds cleaner up top.
