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

easy to install, welded right up to my car. would show pictures if i had some but i forgot to take them. but quality was just as good as you see with valvetronic brand mufflers! almost identical for a much better price!

My opinion, it's a great product! Installation was straightforward with no hassle, sounds good too!! installed on a 2009 Lexus ls460.

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.

Works great, very restricted flow with valve closed (obviously lol), huge volume difference between open/closed. Can cold start in my parking garage at 6am and not wake everyone up!

I’ve had this muffler for about two months everything is good but the only thing I hate is the valve turns off by itself. I searched it up and it says it does that at idle or when your driving and the rpm stays the same for a while. I opened the control box to see if I can disconnect anything to make it stop turning off by itself but I couldn’t figure it out so either there is a way to do it and I don’t know or there’s just no way to fix it so I’m considering removing the whole muffler but still not sure. The pros are the sound is good when the valve is open, when it’s closed there’s a little sound it makes but I’m not sure if it’s from the muffler or one of my old resonators but it does quiet the exhaust sound very well when closed. Overall it’s a good valved muffler, it’s quieting abilities are good and the loudness from before the muffler installed sounds the same when it’s installed and the valve is open. but the thing that ruins the muffler is that the valve closes by itself at almost every stop light and sometimes at random then you have to press the ON button every time

Great muffler, sounds like Borla on chevy Silverado

Does open and close well. And works well in that aspect. But when closed in quiet mode it makes a annoying whistling/ air swooshing sound during acceleration. So I leave it in open mode all the time which at that point I could have purchased a $20 straight pipe.

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.
