I have 3" down pipe with resonator and muffler still on.4 inch resonator back..... i just bought the truck, it has a 4 inch dynomax muffler, how will it sound if i take the resonator off and run the 4 inch dynomax.... also how would it sound if i went with 4" turbo back with the dynomax muffler

 

See how ya like it with just the muffler. Should give ya a nice deep sound. Then if ya want it louder drop the muffler and get a straight pipe.

 

Drop them both off IMO. nothing sounds better than the deep throaty sound of the cummins.

 

AGREED!

I'm straight piped for the last 4 years...
