Its a flowmaster muffler.

I wanna quiet down my LM1 a little. I love the WOT and its not loud at highway speeds really all all compared to how my magnaflow was and I had LTs and ORY with it as well.

I plan on getting a cutout so I don't care about flow.

Its either that or the magnaflow resonator.

 

Or what about these guys?

Ditch the ory then try the magnaflow.
