The manual for JRSC says to use a catback system with there setup... Maybe its bad for turbos but JRSC seems to run fine..

That's becuz a turbo runs off of exhaust flow...so the theory is that a freer flowing exhaust will help spool the turbo faster and less heat will be pushed back up into the motor. With a JRSC, especially at 6 psi, the blower is not exhaust dependent and the back pressure with only 6 pounds is not likely to affect your power as much. The mugen exhaust scavenges well, looking at the loop design. Scavenging is a bigger factor for FI to an extent, but diameter eventually takes precendence depending upon how much you are boosting, etc. The exhaust flow from a JRSC is a more progressive increase in flow, whereas in a turbo setup the exhaust will come in large bursts while in boost, where the scavenging benefits are marginal and diameter is more advantageous.
