just wondering if there are any differences on the two ...my stock pi cracked and i got a dorman to replace it . the runners on the dorman are a lil shorter ...AND BEFORE anyone says why stock replacement instead of trickflow, p51, typhoon, it was not in my budget just needed to get car back on road lol

it should be the same, i dont think theirs a big gain on intake manifolds unless you have a power adder or cams.
