Newb ? here.. I just purchased my evo and it has this BOV on it. I don't know much about adjustable BOV's but I was considering just putting a stock one back on. I think this thing is too loud. Is there any benefit worth keeping it? I don't even know if it's adjusted right but, my quesiton is what does this do over putting a stock ix BOV on? The car is all stock atm.. might do exhaust and MBC but thats it.
