Neither. The N54 isn't a great sounding motor, stock exhaust with the can flap open is as loud as it should be before it starts getting annoying I'll probably set my can flap back to stock once I do cat less down pipes.

I would delete the secondary cats before I would do a muffler delete. I have a magnaflow race system with full cat delete. It is just about right as far as tone and decibel level.
