The truth of the matter is that it is a common misconception that putting on aftermarket exhaust is going to give you more power, well it will at the peak of your powerband, but that is it, but in fact you will lose more average throughout your power band, meaning that it is nly a good thing to do if you are constantly near redline, ie: racing on a track. lets say your cbr puts out 100HP@14K RPM's, well you might go up to 102HP at that same RPM, but lose 5-10 hp throughout the rest of your entire powerband. Aftermarket exhaust companies know this, but only give you peak HP figures to make sales. If you don't believe me look at any before and after dyno. To help a bit, my friend and I have the same exact bikes being 06 zx6r's. His best 1/4 mile time is 11.8 seconds over multiple runs the same day, I was pulling 11.1 seconds on mine, given it was a very hot day. The difference? mine is bone stock, his has an aftermarket exhaust, air filter and power commander, and we run the same gearing and same tires. but on the flip side his bike's top speed is almost 1mph higher than mine, but I'll be long gone before he hit's it. Simple answer is; aftermarket = less power everywhere except on the last 1 or 2 k rpms which means slower off the line and low rpm to high rpm acceleration, and I don't know of too many tracks that you're going to constantly be in your peak rpm anyways,they also weigh a bit less, but not nearly enough to make up for the lost low and midrange hp. Bike Manufactures have a hell of a lot more money in R&D than exhaust companies do, so they know what their doing. So if you're on the street, save your money and make your bike more personable and custom vs. doing what every other idiot thinks is the way to go.
yes they can produce more power or torque but after you change exhausts you usually have to change jets also
A slip on exhaust will give a dirt bike more power. A full exhaust setup will give you even more power than a slip on.
dual exhaust is a start.
The short exhaust should be more efficient and increase power.
It's a turbine mounted in the exhaust manifold to give more power and smoother running to the engine.
An exhaust pipe is used to excrete the co2 from the gas that has been burned in the engine it is usually snakes to thw back or side of the truck so that it is out of the way. If you get a bigger exhaust pipe than the stock one you can usually get some more power from your engine. You can also get an exhaust kit with a switch the can change the amount of exhaust exiting the pipes.
programmer, more boost, larger injectors, intake, exhaust.
change out the intake, throttle body, exhaust, get a tuner like predator, switch to the slp ram air, and cut your egr valve.
The Sport button on the shifter for the 1991 Honda Accord is to change the motor so that it will have a little more power. The RPMs should go up by about 500 RPMs.
It can be done from above or below. Above is easier but more time consuming.
No it will not. If you have more air exhaust going out you have more air/fuel coming in thus more power but less fuel economy. Its a trade off.
Cold air intake or exhaust would be the simplest and cheapest.
