New CMS bypass arrived! Nice pipe!
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.

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.

CMS design has an X flow scavenging effect. They sent me the dyno sheet.
