This is my 2007 Chevy Duramax. I bought it used and stock with 20000 miles on it. For the exterior, I put my chip on it and took off the DPF and put 4" MBRP duals with 5" tips for a 2006 Duramax. Two weeks later i threw a rod bearing and took out the motor. I replaced the motor and put the chip back on it and tuned it up to the 550 HP. Then I went and put on a FabTech 8" suspension lift with 18" DIAMO Wheels and 37" tires on it. i had all the emblems taken off of it and tinted the windows. and last I put on a Fab Four Pre-Runner Bumper on it and painted it to match. And for the inside, I put Harley Davidson floor mats in. I also put a Clarion In-Dash 7" touch screen monitor. Two 10" Memphis Subs under the rear seat run by a 500 Watt Memphis Amp. And that is it for the pickup now but im still going with more power later.
