Hey im getting a 95 civic and idk If I should get a Header or a cat back system...This will be my first mod...what better performance will each one give me and what one is better for their prices...thanks

exhaust system, custom if you can, it will give you a nice tone and i just think that starting from the back up to the front is better,

If you want to take advantage of the air flow I'd recommend saving for longer and getting both at the same time.

EDIT: oops ment to spell "saving" instead of "saying"

If you want to take advantage of the air flow I'd recommend saying for longer and getting both at the same time.

there is almost no point in doing one w/o the other. the cat-back would be better on it's own than a header, but i still have to agree w/ both of 'em

Both

I went through this development cycle with my old MR2, and here's what I found.

Intake, slight improvement in throttle response, not really HP. Sounds great.

Exhaust, sound improvement.

Gutted cat - loss in low end, but increase in mid and high end HP.

Port/polish head + high lift cams - lots of power increase, all RPM's, but believed to be heavily influenced by previous mods.

Its all about opening up the airflow, and there exisits a STRONG relationship between intake and exhaust flow - without head restrictions

If I had to pick one as being predominant, I would say head work/cams.

But remember, what you gain in power, you usually loose in "street-ability" - funky, unpredicatable behavior,

u should do both, and it would help to get an air intake too.

i'd also say both at once. but if your in a rush to get that first mod in (which no one would blame you for) start with exhaust
