If you want loud you won't be happy with the OBX - it's barely louder than stock. The Magnaflow sounds awesome but there is a drone, though you can shift around it if you have a 6-speed. I had the Magnaflow for a while but I'm running the OBX now....pity there a isn't something in between as the Magnaflow is a little too loud for me but the OBX is too quiet. I have a Magnaflow 16633 for sale if you want it.
