Rbj, sounds beast bro! If I end up staying with the 55k I will definitley make another video of the new build for comparison.

For those deleting the secondary cats, did you get a check engine light? If yes what was the fix?

For those of you contemplating the muffler delete. It does introduce some serious drone from 1200-2000 rpm. Adding a j-pipe to the exhaust will almost completely eliminate drone and its relatively inexpensive. Solo Performance has them on a few of their axleback kits but they are fairly easy for an exhaust shop to duplicate.
