A waste of money because if you paid retail for it than yeah. But anyways you only get maybe 2-5 hp at the wheels. And true you'll gain some torque but you'll barely feel it. For as much as you would spend such a header you were better off buying a nitrous kit. For maybe a $100 dollar more or so not to much when it comes to making power. But n/e ways Good Luck on your Honda.

It doesn't really affect sound, you will notice a minor increase, if any in HP or Torque. Headers are really easy to install, you just take off the stock and put on the new, it's usually like 10 bolts, takes 30 minutes.If you're going to buy headers, you might as well get a full exhaust. It's more cost-effective.

Minimal increase in horsepower... if you're after the ricer buzz get a cat back. The guy above me has obviously never installed a set of headers on a civic w/ all factory pieces there because it sure as hell is no where near a '30 minute job'.

small increase in hp if you want a nice sound a good hp gain do as your doing so far, install the headers first once youve done that, then install a cat back exhaust. hope your asking this question before you get the headers, this way you find out that its gonna be alot cheaper if you buy headers and a full catback together at the same time. as far as installation goes, get a pro to do it. not only will you be sure the placed everything properly but they will be able to tell you your hp gains

"a pro" ? wtf is a pro? just do it yourself it is a very easy bolt on..... who cares about hp gain? so you can tell everybody? it only matters if it goes faster. that is kinda the point. and he already knows a basic gain -about 2-5 hp
