Hello, I have an 05 Quad cab with the 5.7 Hemi. I have been looking into getting a cat back and don't know what to choose. I want something deep and mellow, but not obnoxiously loud. I noticed in some catalogs, that a lot of the systems don't work with the spare tire in place. My Wife drives this truck most of the time, so I wouldn't want to lose the spare.

Any suggestions would be appreciated.

magnflows are great thats what i have on my truck and i did not have to do any thing with the spare

MAGNAFLOW or FLOW MASTER hate to say it

is there a direct replacement for the magnaflow... so u can just swap in a new muffler...

magnaflow... :)

from what i understand the magnaflow mufflers are the best muffler out there for free flow design. I would say try out a magnaflow muffler.
