New CMS bypass arrived! Nice pipe!
https://cimg0.ibsrv.net/gimg/rennlis...1e6161bb4.jpeg My new CMS bypass arrived. Scavenging exhaust design. According to their dyno runs there is a 14+hp and 14+lbs/trq increase. Packed nicely with all quality hardware. Will have to wait for spring to to on due to weather for install Here are some pics. Very nice workmanship with hydro-formed elbows. Sound will be like GMG bypass for reference. https://competitionmotorsport.com/cm...he-gt3-rs-911r |

Identical to BBi.

Nice!
I will install mine as soon as I get it! |

Looks well constructed and a nice piece for sure.
But, why are they the only company claiming power increases where as GMG, BBi, Fabspeed, Sharkwerks, GRP, Akrapovic, and AWE don't claim or make any mention of power increases? Everything on the 991 GT3 Cup's shows removing the center muffler actually drops power - center muffler with side bypass being the strongest performing setup. Supercup pipes being the lowest performance which is the setup with no center muffler. |

Very cool, the x-flow design looks interesting!

@waxer can you retain the valves with this setup or no? My point is after installing can you still use the PSE button?
