Be aware, you could get boost cut issues with a catless DP+RP. I tamed it with a manual boost controller. The CS DP is a beautiful piece of work. Sounds brilliant, drops spoolup time by about 50% and radically smooths engine operation.
I did it DP first and had zero issues. Once installing the RP portion though, boost cut/creep issues emerged and had to be dealt with.
You DO want to do a Dashhawk and probably fuel pump internals before you start modding anything on this car, imho.
