How do I estimate my exhaust tube size?
Editor’s Note: The easy to read tube size charts replace our original exhaust diameter calculator for ease of use. Easy Way To Estimate: Your intake system needs to flow 1.5 CFM per engine horsepower, and your exhaust system needs to flow 2.2 CFM per engine horsepower. Good Way To Estimate: Take engine RPM x engine displacement, then divide by two.

All pipes are assumed to be 16 gauge steel. Learn about how individual exhaust components are measured, fit together, and what tools and techniques you’ll need to put together a well-fitted, leak-free, custom exhaust system.
How much horsepower does an after-market exhaust add to a car?
However, that doesn’t mean that adding an after-market exhaust will always result in more power. 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. Here’s how you can figure out what to expect:
What size exhaust pipe do I need for my car?

Is exhaust measured ID or OD?
Most exhaust piping is going to be measured using OD dimensions which is outer dimensions of the pipe or the outer diameter. That means if you were to purchase a three-inch pipe—let's say like the one we have here—the outside diameter of this pipe would actually be three inches.
Is 3 inch exhaust too big?
The general rule of thumb for exhaust systems is, as we said 3-3.5in for 250-350whp, above that 4″ exhaust is the right size, but that's about as big as you want to go, even at the 400whp-500whp level.
Does the exhaust size matter?
The optimal exhaust size is a function of exhaust volume. The greater the exhaust volume, the greater the optimal exhaust size. Exhaust volume increases with engine rpm and fuel delivery. So ideally you'd have a variable sized exhaust pipe that increases in size as rpm and fuel injection quantity increases.
Does a bigger exhaust give more power?
If you thought that a bigger exhaust system meant more power, it's not always true. Some drivers want an exhaust that will improve the sound and look of their vehicle.
What happens if you straight pipe your car?
Driving a straight piped car will produce a drone. You will feel vibrations alongside the loud sound, something that can be uncomfortable, especially during longer rides. Keep in mind that a straight pipe exhaust system is illegal in most states and causes damage to the environment. Straight piping a car is very cheap.
Does muffler size affect sound?
As the volume, cross-section or length of the muffler is reduced the loudness of the muffler will be greater and as the volume, cross-section or length of the muffler is increased the loudness of the muffler will be lessened. Another consideration for sound is the inlet / outlet configuration.

How do I choose an exhaust tip?
The final measurement to consider when choosing your exhaust tips is length. You want your exhaust tips to be seen, but you don't want to create a flaming-hot trip hazard for pedestrians. Make sure to choose a tip that's long enough to vent the exhaust from under your vehicle, but short enough to keep it looking cool.
How many cylinders does a golf have?
The Golf’s 2.5-liter engine is an oddity, as it has five inline cylinders. More cylinders typically give you more power or torque, but it doesn’t seem to make a dramatic difference in the Golf: It produces 170 horsepower and 177 pounds-feet of torque.
How many mpg does a Honda Civic have?
A comparable Honda Civic gets 26/34 mpg and the Cooper an impressive 28/37 mpg.
What is the difference between TDI 2.5 and TDI 2.5?
One regrettable difference between the trim levels, however, is that the 2.5 has no center armrest or storage console between the front seats, where the TDI does — nothing on the floor or attached to the seatbacks. For some people, this kind of thing is a deal-breaker.
Does the Golf 4 door have side impact airbags?

What size exhaust pipe should I use for a 500 HP engine?
For example, a 500 horsepower engine would require a 5-inch exhaust pipe (split into dual exhaust that means a 2-1/2-inch diameter pipe for each engine bank). This, of course, is a rough estimate, and there are several complex mathematical formulas to help you discover the "perfect" size pipe to use for your hot rod project.
What size header for 350ci?
It all depends on your application, as well as your preference. Most stock applications below 350ci can be best served by a 1-5/8-inch primary tube header, where a higher power application will inevitably need a larger tube, anywhere from 1-3/4 - to 1-7/8-inch.

How much horsepower does a 6.0L V8 have?
More specifically, large engines like a big 6.0L V8 typically see about a 2%-3% horsepower increase. Smaller engines, like a 1.8L 4-cylinder, typically see a 3-5% horsepower increase. HOWEVER, exhaust systems have a multiplying effect if you combine them with other add-ons.
Why shouldn't you put stock in a manufacturer's estimate?
The other reason that you shouldn’t put a lot of stock in manufacturer estimates is that dyno results are fairly easy to manipulate. When a vehicle is tested on a dyno, there can be significant variations from test to test without any change to the engine.
Does exhaust add power?
The exhaust system by itself won’t add a lot of power, but combined with an air intake and a performance chip or power programmer you could see a significant increase in performance. You’ll also see a slight increase in fuel economy (assuming you keep your foot out of it, of course).
Is it better to add an aftermarket exhaust system to your car?
Adding an after-market exhaust system to your vehicle isn’t just about adding some more horsepower or improving fuel economy. You’ll enjoy a sportier exhaust note, better throttle response, and hopefully driving will be just a little more fun.
