I've purchased the Grimmspeed Exhaust Valve Defeat Plug and can't find any instructions or video for what exactly to do with the exhaust valve on the stock exhaust system. Is it a complete removal and plug the defeat plug in?
You wouldn't use it with a stock muffler set up. The defeat is meant for people who eliminated the valve completely. You could plug in the defeat and manually push the butterfly valve open and it would stay open.
Good news, I have a new coming from Adam @ Tune + that keeps the exhaust valve open all of the time. I'll be interested to see the difference this makes.
i have an extra valve laying around (on the stock exhaust), just not the stock motor.. it's in the scorpion now. fwiw the valve is crucial on the scorpion. goes from super quiet (probably quieter than stock) to a straight pipe .
I would love to hear that exhaust. I hear that the ETS exhaust is very nice. I see some people just doing a muffler delete and not sure if I want to go that route to save money. I read that in the low to midrange has a not so nice sound when you delete the muffler.
