You don't want to straight pipe a Cummins. The noise is not only unbearable when towing but the sound itself is hideous. Some engines sound good with straight pipes but the Cummins isn't one of them IMHO and the drone will force you to stop at the first muffler joint to have ANYTHING installed.
I agree 100%. Unless the sound of UPS pulling up is total bliss. The PSD sounds horrible too. like it has a hole in a piston or something. Leave it to the rattle if you have to have noise to be happy. I heard a DMax one day with 4" aftermarket that sounded like a turbo charged big block. Not bad but I'm to the age now all I want is quiet. Give me a quiet hybrid 5.4L F250 for a combined 400hp and I'd be happy.
