dumb question probably, should i get an exhaust before header?
 

the thing is, i really want a full cat exhaust, but i also want a header, but i don't have enough money for both right now, can i get the exhaust and then add on the header later (well of course i can , but) would it be harder or more costly to install if i did that... umm.. yeah... and how much hp do you think a header will get anyway.. or a whole I/H/E setup

Looking at installation costs, it wouldn't matter what order you get them in. I'd go ahead and get the exhaust first and add the header later.

umm what type of car do u have? i got my intake first..then exhaust...then im moving on to the header....i dunno what everyone else does..but thats what i did...i guess theres no real order u should get them in...id honestly get a CAI before anything..
