Hi, I am looking to change my OEM exhaust. What is for you the absolute "BEST" exhaust or muffler possible for the Xfire?

A straight pipe is here forbidden so I need a muffler, like Magnaflow.

I went to Youtube to get some ideas' but can't make up my mind.

So what is for you the best muffler possible Name and number of it?
