122 Duel Exhaust 120-130

At 20 paces?

I don't recall any discussion abut a dual exhaust for a 122, and frankly can't see the point of it. You'll get the best flow with all 4 cylinders going into one pipe (suitably joining the individual cylinders with a 4:2:1 header of course). With only two cylinders providing impetus long the pipe all the way to the rear I think the gas velocity would suffer. At best it wouldn't be any better, and it could possibly flow worse.
