V6 owners should never go true dual because you'll lose too much low end torque, and with an OHV you already have a shot in the foot so don't shoot yourself twice. Get a single with an exit pipe of 3"
I have a SOHC with a single out 3 inch pipe and it has worked wonders.
i thought 3" was a little big?? I have always been told that anything over 2.5" piping.... starts losing power.
