Anyone out there put a pro moto billet on there stock 08/09 muffler? If so did you make any attempt to mod the inside of the stocker? What did you think whether you modded the internals or not?

I didnt mod the inside, but as you can see in the above thread, the cone is attached to the stock endcap. I didnt notice any change in performance but it sounded a bit different.
