Im looking into making a Hemi true dual setup. This will be a bolt on kit. No muffler shop makes this (unless they have a mandrel bender inhouse which is rare) and the big companys dont dare make it because it requires you to make a cut behind each cat. Also pricing is in the low $400 for turn downs when i make it.
Here are some sound clips and pix of a RAM MEI setup I did. The Jeep will sound the same for hte most part.
WIth nice headphones they sound great or with quality computer speakers.
True dual with turndowns and no cat.
With full tailpipes. This is a proto so I did not leave those electrical wires on the tips.
