the difference is this


The exhaust sounds pretty awesome but i did wish it had a little lower growl =P. The valve doesn't help too much in lowering the noise at startup, i'd say that it helps it quiet down the initial cold start idle sound.
The sound is definately not obnoxious! You also get some turned heads from the exhaust notes haha, its definately smooth.
