Muffler opinion

Same here. I'm running dual 3" with an x pipe on my 5.2 in my Dakota. I have dynomax bullet mufflers right off the headers and magnaflow just in front of the axle. It sounds awesome. Nice deep tone at idle and not loud.

I'm sure it sounds fantastic but it has been proven that a little bit of back pressure builds torque.

As for open headers, merge collectors and short extensions 11-18" long have also proven to increase hp.
