I was torn about installing exhaust cutouts on my CTSV Coupe, I heard from some folks in NH that it was illegal and wouldn't pass inspection. I dealt with those types of issues on a modded BMW 535I Wagon that I had and did not want to deal with the hassle of hustling for an inspection sticker.

So, I went the mild to wild route. I heard that some corvettes have a "mild to wild" system where there is essentially an exhaust bypass integrated into the muffler and can be turned on or off with a button. I liked this idea but there were no kits available on the market for my CTSV Coupe, therefore I made my own. At the touch of a button the exhaust note goes from relatively stock to what this beast should sound like.

Build details:
Cut from the primary Cats back
2.5 inch stainless steel
Straight pipe (no X-pipe) I may add one back in
Xforce Varex electronically controlled mufflers
Xforce Exhaust tips
Tire Wheel Vehicle Hood Automotive tire

Curious on these mufflers, a ton of people just have electric cutouts but I have heard reliability isn't great, after a while they tend to seize up but if these have the actuator all internal to the muffler maybe they will last?
How much were they?

I paid roughly $280 per muffler and had the Exhaust shop use the bolt up flanges so I can drop them out and replace if they fail. I will make a closed and open exhaust note video and post it.

Very interesting and unique setup. I'd be curious to see what the inside of the muffler looks with the valve open vs. closed.

That is the one. Tucked the electronics right up against the underneath of the car, nice and protected.
