ANY OF YOU GUYS TRY PLAYING AROUND WITH THIS. LIKE DRILLING IT OUT OR MODIFING IT. WHAT ABOUT REMOVEING SIDE SOUND SHIELD ? ANY PERFORMANCE LOSES OR GAINS. WHAT ABOUT SOUND WITH SIDE PACKING REMOVED. I AM GONNA PLAY WITH SPARE ONE I HAVE. 3:16 (yammie tony)

Tony, I think the side shielding is just for heat protection. The only way you are going to get any performance (if any) is to cut it open and gut it.
why not, I hear it works on a stock vmax4....

I know fix use to do a muffler mod and people have dynoed it and there was no gain at all but didn't lose any hp.On a ported motor or 780 there probaly would be a gain.
