I contacted Rip yesterday, and he made a GREAT deal on a 4" setup. Talk about fast customer service!! I am gonna get it ordered this afternoon. What I did was order it "mufflerless" but now I am wondering if I should get a muffler due to the noise factor, not that I'm going to complaun, but somebody else in the truck might (and you know who that is!) So, maybe I oughta order a muffler.
What do you guys that have Rips system think?
