I'm looking at getting a cat back exhaust from Magnaflow. It's a single in dual out part # mag 15863 for a Quad cab 4x4 short bed HEMI. Ihave 2 ?'s. First does anyone with this system experience the hiway drone I keep hearing about? Also I have the optional 32 gal tank will this system clear it? Thank you.

 

I can't help you with the drone question, but most exhaust systems I have seen (dual and single) run along the passenger side of the bed, which should bypass your fuel tank with no problem. You could probably get a detailed picture of where the pipes run if you check out their website.

 

Thank you
