From what is understood, being that it was designed for the 335iS, it has a more aggressive sound than the standard N54 335i stock exhaust, and it is more free flow.

So its an in between of the standard and the PE....

I encourage all to research this though, just dont go by what I myself researched.

For a fact though it sounds wayyyy better than the N54 standard stock axle back exhaust
