i was just wondering if anyone could tell me why when i changed from the stock pipe to a alluminum one my car seemed faster but didnt get as hot.....this may sound dumb but im curious....and would anyone have a old pullstart that works that they might want to sell...

better flow, less restriction, and the fact the pipe is aluminum.

what kind of engine do you have? if u have the vertex 18 here for a good price

dont buy a used pull starter unless its like $1, your better off with a new one.
