If the truck is off the valve is closed. Turn the opposite way to open.

The truck has been sitting for over 24 hours and the valve turns in either direction.

One way will turn much farther than the other. Think of the butterfly valve as facing N and S (up and down) and you want it perfectly horizontal, or East-West.

Fyi folks- dynomax vt with a 7000lb trailer is still great with no drone.

Found a shop open on Saturday and had 18" Magnaflow dual to rear with 3.5 tips. $360.00 Sounds great and didn't notice any funny AFM noise. When off the gas or coasting it does make a slight flutter sound someone had posted about.

The flutter is what bothered me about the Dynomax VT, very noticeable to me with the throttle barely pushed in V4 mode. Plus sounded like stock at idle.

After install I used M5 and M6 around 60 - 65 mph and didn't hear anything when in 4 cyl mode, but I have hearing loss. Correct me if wrong seems I read the third cat is dummy and hallow and that it causes the flutter

I am not sure, could be. My truck does it with the stock exhaust but the aftermarket muffler just amplified it. The good thing about the Dynomax system is that if you don't like it then they will let you send it back to them for free and they will refund your money. Took a long time to get my check from them but if finally showed up last week.

i built a dual exhaust using all dynomax parts and a vt muffler . #1 it is noticeably louder than stock. #2 it still drones but it is better than most systems while using v4 #3 after a few months it would rattle at first start up so annoying that i took the muffler out and removed the flapper inside. #4 nothing gets rid of the drone like elimating v4 mode all together. ..my humble opinion

How do you remove the flapper in the VT muffler?

Nice welds

I pounced the flapper out with a 4lb hammer and a pry bar. The only problem is then you have a loose spring and a lever.so on a dual outlet muffler you can drill hole on the inside of the muffler to get the pieces out. On a single outlet this probably can't be done. Granted I did all this at the spur of the moment and to save me from buying another muffler.which for me worked. My muffler was a couple months old.

3rd cat is not monitored and it is NOT HOLLOW... It has media inside and can be drilled and knocked out really easy.
