Does an exhaust improve performance?
A performance exhaust can free up some of the power in your engine by allowing the gases to escape a bit easier. When the gases can escape, your engine runs smoother. Anyway, when the exhaust flows better, the fuel and air exit the combustion chamber faster and new fuel and air can be burned to create more power.
How can you improve performance on a vehicle with the exhaust system?
When your engine is at low RPM, the amount of exhaust gases leaving is low, so the velocity it exits the exhaust is low. You can increase this velocity by using a smaller pipe, but this will create a restriction for higher RPM.
How much horsepower does an after market exhaust system add?
Depending upon your vehicle and the system you choose, an after-market exhaust can add as much as 50 horsepower or as little as 2 or 3 horsepower.
Why do you need a performance exhaust system?
Performance exhausts are a great way to improve the power, and sound of your car! Even with just a sports exhaust back box, your car can sound like it means business and have a noticeable improvement in power. For the maximum power increase though, a full exhaust system is the way forward.
How can I increase the velocity of the exhaust?

How are performance exhausts supposed to reduce horsepower?
This reduces available oxygen and decreases horsepower. The best performance exhausts, though, are designed not just to reduce back-pressure, but create partial vacuums, Road & Track explains.
When your engine is at low RPM, the amount of exhaust gases leaving is low, so the velocity it exits the exhaust is low. You can increase this velocity by using a smaller pipe, but this will create a restriction for higher RPM.
Which is better boost or exhaust manifold backpressure?
Stocky is on the money…..2:1 or better (exhaust:boost) should easily be doable with a half thought out turbo selection though. Getting close to the magic 1:1 or better is only really doable for a race setup that can use a long extractor style exhaust.
When to upgrade the exhaust system in a car?
If this is a dedicated car for spirited driving, it can make sense, even in the case of a stock car, to upgrade the exhaust. If you’re keeping the engine within the higher RPM range while driving (such as on a track), you’ll benefit from the lack of restriction the larger exhaust provides.
