I have a 2010 GMC CC 6.2L

i want something thats louder than stock, but not crazy, still want it to be 3.5" and i want to beable to dump it after axle, my last truck i just cut the stock pipe after the axle....

from being under there it looks like the stock muffler is 3.5 offset/offset
magnaflow only makes a 22 inch muffler that is offset for the 3.5" exhaust and i think that is going to be a little to quiet for my taste.... any opinions??

 

I love my Magnaflow, here is a link to my thread when I first installed it with the stock tailpipe was still in place...

Do you have the part number for that muffler by chance?

 

11219 I believe. It's not polished, just a 14" oval, 4x9 case I believe. I can measure it tomorrow am to make sure. I have since dumped it and I love the sound, its loud for a muffler only.

I liked the way it sounded with the stock piping left in place.. I am probably going to try it out, if not ill dump it like you did.. Thing sounded mean WOT..

 

I love it. It has a nice rumble to it

 

If I can get parts for a diesel and get it off my lift I'll let you know how the 14909 magnaflow sounds with all stock parts in place. Probably be thursday though.

 

let me know... thats the one im looking at... im pretty sure that one will fit.. thats the only 3.5" they make that has an off center inlet.. i really would like a 14 inch one.. im afraid the 22 inch one will be too quiet.... let me know and O your gonna need some more 3.5" pipe.... the stock muffler is 26" long

thanks
