My truck is a reg cab short box. Not a lot of room under there for four mufflers. I can't believe no one makes these for applications other than vettes. How many vettes are out there compared to all the other possible applications? These mufflers are about $1300 a set from GM. I don't know what the B&B setup runs, but I would bet that it, and the GM NPP's, are not much more, if any, than a Corsa system. Someone in the exhaust industry is missing the boat here. Being able to control the exhaust note is a blast. When I'm alone, it's usually in the loud mode. I have the wife trained to open it up on all freeway onranmps and underpasses when she's along for the ride. Passing mustangs also gets the loud mode.

The Z06's bi modes come stock on the 505hp Z06's. The NPP's are an option on 430hp LS3 non Z06 vettes. With the NPP mufflers, the HP rating goes up to 436. How are the Waldron mufflers switched from quiet to loud?

The waldron mufflers use a dash mounted switch. They are vacuum operated just like the npp's. The npp's are just old tech rehashed. GM pulled the plug on those in 1970 very shortly after introduction because they were driver operated. Since they are now automatic, I guess GM figures that it is OK. Anyway that waldron muffler is a traditional style muffler like a turbo muffler.
