You know I just realized that I have the Apexi Ws I exhaust wich is no longer made. I wanna know how different the WS II is from my O.G.
WS I....


Anywho I'm able to run a Greddy header with a test pipe and the Apexi Ws I from the cat back and the engine screams louder at wot than the exhaust does. I love it I can creep around quietly with all the benefits of an aftermarket exhaust. I don't think it could be set up any better.
