Akra is a bit too tamed for me. It's appeal is the construction and lightweight. But in sound category,this is a bit subjective category but the mastermind x mxp takes that category by a landslide

In all fairness I was using the challenge street pipe. This basically utilizes your factory primary cats and only removes secondary. In other words, a factory x pipe with modifications mainly for sound. I'm sure if i ran their race or race + it would of been a completely different story...

sounds like the Challenge Xpipe from THESE tests, didn't do squat for power or torque. Interesting.
