Howdy fella
I'm over here too
(sometimes)
I'm thinking I MIGHT wanna look into stepping down to a 2.5" exhaust kit rather than 3"...it'll give me a tad bit more clearance...more low end grunt...and maybe fit better if I get a pipes w/ Xpipe kit....maybe just do some adapters to my 3" mufflers

.....then tail pipes out to the back.
Right now it ends at the back of the mufflers (no turn downs). Still scrapes and its as tight as I can get it to the floor.
BAND CLAMPS are my next BIG investment (that and some anti sieze on the pipes).
Hook it up !!!!! (post pix)
