BF XR6T / F6 STAGE 2 – 330-350RWKW
1 in stock (can be backordered)
Our Stage 2 package includes everything from the previous package, but includes an even larger intercooler kit. On top of all this, we address the exhaust system restrictions, so we upgrade to our PR Spec Turbo Dump Pipe, Catalytic converter and catbcack exhaust to let the big 4.0l turbo engine breathe. With this comes the need to improve the wastegate flow and the valve spring strength to combat over boosting and valve float, both of which can have catastrophic effects to your engine.
