Help me out please

I have a 2005 Civic EX and it is completely stock and I was wondering what should I do to it first? Mainly I want to get more Hosepower and torque.

Welcome to AF. Your Civic has a D17 engine SOHC so you will not be able to pull to much power from it unfortunately with only that one cam. You can ad a bit more pep by adding the usual bolt ons. Look for I/H/E intake, headers and exhaust. Intake and exhaust will give you nice sound and make you feel quicker but your numbers wont jump to much. If you really want speed throw a bottle on the car with a small shot 25 or so. Turbo and swapping are you other options but then you taking much more money and knowledge. I'd stick with a nice cold air intake and full cat back exhaust maybe some springs and you got yourself a nice ride. Try to not remove you cat because you will need that back pressure. Watch double posting and goodluck!

the muffler on this car is bolt on, and easily removed in about 10 minutes. I can't remember if the bolt is metric or not, it's either an 11mm or a 1/2...anyway, I took mine off and it sounds as good as any aftermarket system and there is a definite gain in low end torque. and it's free. Honda factory exhaust ftw.

hosepower. heh.
