i've been thinking of putting in a bigger exhuast in my car. right now i have the stock exhuast on the engine. i upgraded my carb to a two barrel and some one was telling me about back pressure. dont know much about it. the engine is a 170 ohv, 63 lark. like i said the exhuast is stock i think it's 1 3/8. does anyone have any insite on this or suggestions.

Easiest way to reduce back pressure is to use a flow thru muffler like a Cherry bomb.
