A tuned header with a open chamber muffler with a short side dump exhaust pipe has the least amount of back pressure. It may be so loud you may get tickets and ruin your stereo music sound.

Well the other guy who answered doesn't know much. Tune a header? It's just a pipe, nothing on the part to tune.































Anyways, get a header from reputable company like Skunk2. Header is important not to go custom because the routing of the piping from each cylinder is important and should be left to professional engineers.































You can either opt to get a full catback exhaust system from the same company, or get it custom made. When getting a custom made one, try to make it as straight a pipe as possible, with no angles larger than 45 degrees. Also, make SURE that the exhaust tip/muffler has good clearance from the bumper so it doesn't melt/burn it. That can be a real headache.































Get a high-flow catalytic converter and that will free up some power.































Total increase in HP should be around 5-8hp, depending the choices you make.































PS. For the piping I would suggest a 2.5 inch exhaust, anything bigger will give you tons of torque loss, and seems to be the ideal width for NA applications.

aznkevin is wrong about not being able to tune a header because it's "just a pipe", as the shape, length and when they merge all affect power. However, I will say this much. The old tale about large pipes killing torque is a myth. The most important thing is that they merge well, after that you want to reduce pumping losses as much as possible. The problem is, that a small 4 cylinder like a DC2 1.8L will just be obnoxiously loud with larger than a 2.5" pipe. A 2.25" pipe would work fine on it. A 4-2-1 header will make the best torque for your car.

4-2-1 headers make more midrange power, 4-1 makes more top end power. and no you cannot "tune" a header...how are you going to do that? its fixed pipes that dont have anything you can control on them. they are engineered, meaning they go through testing to see flow rates adn how they work with particular engines, but there is nothing to "tune" on them. anyway the overly large exhaust piping is not a myth. on a steady flow of gas yes this would be true, but have you ever looked at the exhaust of a car? its a pulse time with the ignition of hte cylinders and the lift of teh ehaust valves, not a steady stream. the hot air in the exhaust piping creates a vacuum that helps suck the gasses from the combustion out of the cylinder and through the piping...too big, and the vacuum wont be created, meaning that not as much of the gas (gas as in the result of the combustion, not the gasoline going into your engine) is getting sucked out and your engine has to do more work for the same result. this is called scavenging and is definately noticeable on low RPMs. so yes you CAN go too big. you can also go too small when choosing an exhaust since it can back up.















if you have a stock engine, exhaust is not going to be worth your money to upgrade, especially on an integra LS where teh stock exhaust size is roughly 2" diameter. if you're doing the I/H/E route then i would aim for about 2.25" for the catback. you dont need a 2.5" unless you're running low boost or are doing an NA build on your engine (high compression, etc). only time you need a 3" or larger is when you're running medium or high boost.















if you're looking for exhaust headers, just keep in mind that 4-1 is more high rpm power and 4-2-1 is more medium range rpm power. as for companies that make them, there's several reliable ones out there: skunk2, greddy, apexi, dc sports, etc.
