Matching exhaust manifold to exhaust port?
This is probably a dumb question, but is the stock HPI manifold rectangle supposed to be dramatically different than the engine port?
Would performance increase or decrease if I matched these?
I just noticed this after an exhaust leak developed at the gasket interface due to loose screws.
Any help for a newbie to nitro?
