I have the K&N air filter installed now, and V&H slipons on order. Which is the correct PC V to order? I see one with an O2 senser for 250 and one with just the PC V unit for 329. I don't need to go all super fast mod, and don't need a super intake system.I only want my 2011 voyager to perform well and sound great. As of now i do get a lot of popping on deceleration, but it seems to do well on acceleration. The Vorager only has 153 miles as of today Any help is appreciated with website if possiable.
