2.5 Inch Valved Muffler Exhaust Cutout with Muffler Cat Back Exhaust System Kit

Low rpm with the valve closed it’s muffled well but at higher rpm it’s not very muffled. It’s still a very good valved muffler either way for the price.

Installed on my daughter's 07 silverado 6.0 and it sounds great and she can leave early in the morning with waking the neighbors! Works perfectly.

Seems very high quality, welds all look good. Slightly louder than the stock muffler closed and sounds great with the cutout open.Found out they have a button I am going to install too, making it look more OEM.I hated how all the major guys charge 1500 dollars for a system that honestly I feel sounds like hot garbage if it is valved (MBRP for example) but sounds awesome if it isn’t valved. I wanted both, so I risked it for the biscuit. I’d rather have the plug and play but I listened to all the major valved companies and didn’t like any. I actually thought this was a valvetronic muffler when I bought it I but decided to risk it since this system is probably made by the exact same manufacturer as valvetronic. Had it professionally welded on since my welds aren’t perfect and it’s on an R- the rest I did myself. Easy install. We’ll see how the button install goes. I’ll post a video later. - my only gripe. It smells like the fiberglass inside is burning off after the first couple drives, so we’ll see how continued quality is. If this wasn’t the case, 5 stars all the way.

The media could not be loaded. Very very impressed. Despite the comical brand name(!), these are seemingly very well made. Good, thick gauge steel and consistent welds all around. The compressor kit worked out of the box, the two remotes work perfectly fine! The switch in sound as the valves are opened or closed is significant, in my case, it takes approximately 2-3 seconds to switch from closed to open. Very much recommended kit!!!

Such an amazing muffler! The ability to sound stock or modified on a 3 inch turbo back exhaust is amazing! Highly recommend if you want the best of both worlds!

Great price, great idea. But the closed section is a 90 degree to a 2” pass through pipe. Felt like I lost 20+ horsepower with the muffler closed and it makes a loud whistle noise on wide open throttle closed. BUT it works great for quiet/loud idle and quiet cruise. Will probably remove and go with a name brand Valvetronic just for he larger pipe.

Would definitely buy again, better than Valvetronic i had before

Garbage. Installed and it is only very slightly louder then when closed. It should sound like I have no muffler on when the valve is open. (I have a v8 turbo). With no muffler on its super loud, I put this on and open the valve and it basically sounds like I installed the stock muffler back on. Waste of time and money!
