BlackGMC, I ran the 12579 dumped before the axle and it was real quiet. I had stock cats, but I'd imagine over the axle out the back it would be pretty quiet without cats.

Yep, i will be getting rid of the oval muffler $15 and it is yours (you gotta come pick it up thou), but i think i am going to keep the 5" round one and put it infront of the monster i just bought .

the biggest flowmonster muffler available is the 18" case, 24" overall length muffler. the 22" case is still in the works. i had that same muffler on my truck for a while and its quite a bit louder than the magnaflow he ended up getting. it would probably be louder than his current set up as well

I couldnt remember how long the case was. I love this muffler, so much deeper than the 40 flows.
