1. Looking to put a muffler on not full system just muffler, Goin to go with magnaflow 18 inch, wondering what size tubing is on stock. My 07 was 3 inch so just makin sure before i order is it 3 inch single in dual out.

2. Will my Sc cortex tuner from my 07 2500 work on this truck? I put truck back to stock before selling it and kept tuner, will it work?

Thanks

 

Anyone?

 

I have a Magnaflow 18" welded on in my 2009 Hemi. Love the sound. I am 90% sure it was 3" in and dual 2.5" out. Unfortunately, I don't have the box.

I just installed the 18" Mufflex kit which is just the Magnaflow muffler and clamps. Total 3 clamps/bolts. Easy do it yourself. Sound rocks.
