I would NOT do the straight pipe. There are aftermarket exhaust that do as good of job letting it exhaust and sound good. A straight pipe will drive you nuts running down the road with a load. I have a MBRP exhaust on my 05 and really like it and has no droan.
Gee-buzz guys!!
Straight piping means to do cat delete...still run muffler! Then buy the Smarty Jr. safest programmer on the market and designed specifically for the Cummins.
