I deleted the muffler, have a straight piece of pipe instead, and kept the resonator. Sounds great with a bit of drone though. I'm happy!

Consider the OEM resonator delete pipe instead of a shop welding in one. The stock option is bolt on and easily removable if you don't like it.

Thanks for linking that thread. Just read through all 35 pages. Lots of videos. I like the one the guy has the 18" Magnaflow with and without the resonator. After watching that it seems that a good compromise is the 14" Magnaflow with resonator.

Hey sorry been busy! I tried to get a good sound bite today as I just got the resonator installed, but sounds like garbage with my iPhone.
What I can tell you is it totally eliminated the drone and overly loud exhaust note in the cab! Now it's that nice deep magnaflow tone and loud when you get on it.
