That is the one that I bought. I left the baffle out all together. It gives it more throttle response, but it is a little loud (stock muffler). I wanted to try it with the baffle in, and plug out. But I was afraid that if I wanted to take the baffle out, it would not be easy to remove after going through a few heating cycles. I will live with the noise for now, as I plan on getting the ecu tune and will need that extra flow.
