it's possible....these days exhaust manifolds are so restrictive you can really free a lot up

so will the header from ebay will give about 15 WHP? how much should i expect from header, highflow cat, resonator, and 2.25 all the way to the straight thru muffler?

all of those together might get you 12whp. and that's it. BETA's take real bad to n/a mods.

check the link he posted, its for a 2.4 altima

and i believe it because ive driven an altima and fr a 2.4 its slow as HELL. somethings gotta be holding it back and a good guess would be the extractors.

opps i'm dumb.
:nervous:
but i still dont' think they'll get that big of a gain. that's like 21 horse at the engine.:ermm:

, i will proly dyno my car after exhaust and pulleys

and i already got CAI

12 WHP is like a 10% increase over stock. This is probably about the same % increase as you would see for a Mustang or similar car, only they are at much higher HP to begin with. It's not that the Beta responds horribly to NA, its just that you can only do so much with a 2.0L engine without force-feeding it or spending incredible amounts of money.
