looks great, i wouldnt mind putting my w/g back to the dp one day.. half the time i like it loud, half not.
its cool that the 4" fit that k member/mount combo.. is the housing 4"?
dont forget to cut the rest of that alternator bracket post off. and i have gone through a couple reman alternators since 2004 when they did the first race kit for me & i HIGHLY reccomend wrapping that header. george put some on mine originally and it got cruddy and i removed it and started losing alternators.
i am pretty certain you can get an elbow and a filter on there just like what i have if interested
