Well I got my Pinnacle Power exhaust on, along with the Aero Turbine "non resonated" 4040 muffler "Diesel Power Products" and a 5" double walled MBRP tip and couldn't be happier!!! It's got the 12 valve stright piped sound, but is nice a quite in the cab! I ordered the Pinnacle exhaust with no muffler "cheaper that way" and cut the Aero muffler in. All my buddies are
about the system. The only bad part is with the added boost from grinding down my stock fuel pin and I'm sure adding the exhaust, I now 30lbs of boost. I'm about to slip the transmission, so I have to cool my jets. All and all it's a good system!
