I believe i have the PV2 w/ catback. It's Ok sounding. Nocturnal and Mr. I-Man can attest. Money permitting I'm looking for the V8 truck sound my neighbor has with his magnaflow. Can i get closer with a differnt tip? is this something that needs to be welded on? Or do i need to go dual catback? I think Mr. I-man suggested this to me before.
