Upgrading the mufflers is an easy do it yourself job if you buy the ones that are made for these cars. I only needed a shop to do the work because I did not have a lift, cutting equipment and pipe expander needed to install the x-pipe.

I would love to hear some live sounds of various 4.0 V6 models with different mufflers.. But no You Tube videos... I cannot tell squat from those.

 

I really wish I just had the muffler shop just run everything straight back dual with no X or H pipe. You always learn more after the fact.

You know I also took one muffler off and started it to see what it sounded like. Of course it was horrible.
