Challenge was the undisputed king of the E9X X-Pipe, but they became virtually impossible to procure. With RKP’s timely acquisition of Challenge, they have elected to bring this sought-after piece back in all the right configurations, but with some notable improvements in production.
What it Does: It has to be said that the S65 is one of the best sounding motors from BMW’s M division and the RKP X-Pipe helps it sing on song in all the right ways. By foregoing the secondary (unmonitored) catalytic converters and replacing the primaries with a hi-flow cat (or eliminating them altogether) the S65 screams as the BMW gods would have intended with the added benefit of significant power gains. Win win.
Defining Features: Achieving the perfect sound is all about careful calculation and placement. Where you place the “X” and its accompanying primaries (where applicable) make all the difference here and RKP has it just right. RKP’s production improvements and impeccable welds also guarantee that this X-Pipe will easily be the highest quality piece on the market.
