Default 2005 LS2 dual mode exhaust

Can you put a Dual Mode exhaust on a 2005 with an LS2?

All you need is an NPP exhaust from a 2008 car (2009+ is different) and run a tube up to a vacuum line in the manifold.

I'm not sure if you have an Auto or Manual, but you can get the Z06 bi-mode exhaust to fit as well...likely easier with the manual transmission.

Just remove the original mufflers and install the NPPs. You'll have to unbolt the brackets for the rear sway bar (4 bolts, I think) and push it out of the way, and drop the center pipes. Using a lift, a friend and I did it in an easy afternoon. This included installing a Mild to Wild switch. Great upgrade. I think I paid about $700 for the NPPs (they were used) including shipping.

What is the difference between the Z06 Bi-mode and the NPP?

I would guess the Z06 would be 3" over the axle pipes that neck down to 2.5" at the muffler???

What would be the easiest way to adapt the Z06 muffler, use the stock (LS2) over the axle pipe and weld them at the muffler??

They have a mild to wild switch. You can here the sound on Corvette Central site. On the quiet side a little louder than stock on the loud side about the same as the Bullet Exhaust.

The mild to wild switch doesn't change the quiet side.

When they're closed they're closed, unless you install a clip or something to manually keep them open a certain amount.

FWIW the Fusion's are one of the few aftermarket exhausts than are heavier than stock.
