Aftermarket Dual Mode 3" Mufflers - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

For some reason, I'm having a hard time finding some aftermarket dual-mode mufflers.

I have the NPP from GM, and have recently installed some headers and 3" back to the mufflers. I had to cut them right before the hangars, and it's all set, but I was considering purchasing some 3" mufflers.

I love the dual-mode mufflers since it allows me to be quiet when I want to be (such as driving through my neighborhood at 3am).

Does anyone have any links or suggestions on where to find JUST the mufflers? It seems like I can only buy the cat-back system, or when it's just the mufflers, they're not dual-mode.

Also, does anyone have suggestions on some hangars I can use? The new 3" pipes are hanging lower than I'd want them to (even after raising them before tightening the clamps).

Thanks in advance!

Billy Boat is the only 3in exhaust system that maintains the dual mode function. The B&B system is a catback.

Muffler only I haven't found anything, I don't believe it exists.

Edit: I forgot about the Z/28 exhaust but that is a 2.75in system, not a 3in
