since i live in southern california, i can't go with no muffler. i'd like something that is less restrictive, and produces a good deisel sounds. are there any recommendations for muffler brands and models?
thanks for the help.

Here is an article that was just published on the 6.9 and 7.3 NA exhaust mod.
Nice pictures, and it is what needs to be done for much better flow.
I like mufflers that you can see straight through, but you will have a louder truck and it will have a jake brake sound when gearing down with the engine between about 2700 and 2100 RPM.
With a NA motor, and the extra cost of 4" pipe, I think I would go with 3" from the Y back.
