I bought a "matched set" of 340 exhaust manifolds and to my surprise and disappointment one side is only 1 7/8 outlet. The other side is 2 1/4. When I saw it I told the seller he gave me a wrong side, he says no, that is a factory numbers matched pair.
Why would Mopar do that? Won't that make the engine off balanced? I had planned on running 2 1/2 full exhaust.
Thanks
Mark
