So I just bought a set of ZZP headers and 3" dp, I currently see 5-6* of kr with my current mods, can I expect to see that disappear and possibly drop pulley size?
Reuse the stock manifold gaskets and buy a Felpro gasket for the catback.how are those headers? you have any issues installing them or any leaks? and also does it come with new gaskets and possible new hardware?
