So I'm thinking about having the NPP mod done to my mufflers( pulled the fuse already ) anyone know of a good muffler shop around Orlando that could/ would do this and not charge an arm and leg to do it.
I'm not sure what the mod is that requires the muffler shop, but if you have pulled the fuse I highly recommend going over to C6 tech and searching "NPP switch add a circuit" which outlines making a switch for that fuse connection you can mount it then anywhere you wish in the cabin. It was simple and even fun to make, pretty ingenious really. GL

Its where you cut the sides of the muffler out, and have the inside perforated pipes either replaced with a solid pipe,or clamp a solid piece of metal around the pipe and weld the sides back together. It's said to make it louder and have a deeper tone for ALOT less than a catback.

Thats for the Bi-Modal Z06 mufflers, not the NPP. They have different configurations inside the mufflers. Not needed on the NPP, it's as loud as it can get.
