Yeah, RR Racing does phenomenal work. Best out there for the "F" platforms right now. If you don't have their LCA bushings for the F, you need to get them.Nice I own an ISF now and your spot on the sound is amazing lol no comparison to the stinger there.... I personally like the F better but love the Stinger as well. I just hate that there is real aftermarket support for the F. And only one company has a supercharger out and can tune it.
