There are 2x main configurations available for E6X M5 & M6 members to achieve their desired performance, sound, and weight targets.
|Resonated Cat Back
|Unresonated Cat Back
|F1 Race Rear section
The X pipe (Section 2) & Rear Mufflers (Section 3) are a sound enhancing modification first and foremost and provide no performance gains.
I personally plan on running the F1 Racing Mufflers alone as I already run catless long tube headers. If you plan on retaining the stock headers, I would recommend the unresonated cat-back to unleash the V10 noise.
You can hear the differences in configurations here.
The S85B50 can be uncorked and performance gains can be found in the header section by improving its design. I have not curated the Supersprint headers as I prefer the Infinity Design V3 Headers for its equal length design and lower price.
