I want to reduce the exhaust noise in my 2003 Dodge without creating too much back pressure. Currently, I am straight piped. I thought the exhaust was supposed to be 3.5 inch from the engine to the muffler and 4 inches from the muffler down stream. Mine measures 3.75 inches outside diameter all the way through. I was thinking of installing a 51 inch Donaldson Muffler which is 10 inches in diameter with 5 inch diameter ends which I have read works well. It appears I don't have room for the muffer installation without custom bending some of the pipe. Has anyone out there done a similar installation? I have searched the treads but still am confused.

If you want it quiter, you got to muzzle it. At least try a resonator back in system
Add some more sound deaden material to floor and back of cab.

Yep- I put a 51" Nelson on an 03. No new bends. The exhaust exits a slight bit further back. It looks great, and less soot on the fender. Nice mellow tone, and not much louder than stock. No restrictions.

Thanks for the advice. I will go with the 51" Nelson. I guess it is time to learn to use my son's wire feed welder and set my stick welder aside.

There are still some pictures of the 51" nelson on the 03 in my profile.
