Fabspeed XPipe with Resonators verse Active Autowerke X-Pipe Gen 2
-Horsepower/Torque gains?
-Loudness/Drone?
-Any CEL?

Thanks!
comparable product.... both should come in right about the same on HP/torque. volume should be the same. AA claims to have new HFC's that don't give a CEL. Fabspeed claims no CEL too, but almost everyone has gotten one at one point or another. I have gotten a CEL twice with my Fabspeed, but it will clear itself after a few hundred miles. I think their price is a bit better than AA
