I live in a non amish state, but decided to keep them for now. Added mbrp hotside pipe and down pipe as well as 4"cool dual which delete the muffler. No in cab change in sound with windows up, slight rumble from exhaust and a noticeable change in turbo whistle with windows down. I run an Edge Evo CTS2, love the gauges and could return to stock program if emish nazis invade.Still noticable by dealer if they bother to check. Level 4 full throttle makes me an A hole driver as it burns all 4 rear tires going into 2nd gear. 1st gear stock turbo won't let me spool up fast enough to lite up 1st gear without a boost launch. 4wheel high 8-10 psi launch is stupid, but hard on the tranny.Thinking about a Batmo or wicked wheel to fix that. I would like to see them find that... Looking to go with a lift pump next as I drained the fuel rail at wot and 110mph and my fuel filter milage went straight to 0% with only 3000 miles on new Parker/Ranco filter. For the most part I drive like a civilized person but can't resist the urge to flaunt it sometimes. Also no black smoke whatsoever, not to into that as it seem like a waste at the current cost of diesel. All in all I am happy with my 7000lb hot rod when I am not playing family guy pulling my 38ft home away from home.
