What is considered a modified exhaust?
Are all exhaust modifications illegal in California? Exhaust modifications are illegal only if noise emitted is over 95 decibels. Keep in mind California smog laws or other legislation may still make your custom exhaust modifications illegal. All vehicle exhaust systems must have mufflers.
Is it illegal to modify an exhaust?

How does exhaust technology help reduce the problems?
Contemporary exhaust technology can help reduce the problems and help to maximize the potential gains of the system.
Is the exhaust system an afterthought for car builders?
All too often the engine exhaust is an afterthought for the engine and chassis builders, yet its design and construction impacts significantly upon car performance.
What happens when the cross sectional area of an exhaust pipe changes?
Whenever the pressure wave encounters a change in cross-sectional area of the pipe, a reflected pressure wave is generated, which travels in the opposite direction. If the change in area is increasing (a step, collector, the atmosphere), the sense of the reflected pressure wave (compression or expansion) is inverted.
Is it necessary to filtrate the exhaust system?
HEPA filtration of the exhaust is generally unnecessary as the exhaust effluent does not re-enter the room, but the author recommends coarse (>30 percent) filtration to prevent build-up of debris in the building’s exhaust system.
What happens when you change the exhaust system?
In some cases, you’ll shave up to a full second off your acceleration time from 0 to 60 mph because the Edelbrock design improves your engine’s ability to breathe. Mileage may also improve, as your engine becomes more fuel efficient.
Do you need to change the exhaust system on a motorcycle?
As a general rule, most slip-on or “muffler-only” exhaust systems do not require alterations in the fuel delivery, but even a bone-stock factory motorcycle will benefit from fuel management changes. If you are purchasing a full exhaust system, most manufacturers strongly recommend fuel system changes.
Which is the best exhaust system to upgrade?
Axle-Back Exhaust Systems – Axle-back exhaust systems typically begin just before the rear axle and include a muffler (s), tail pipes, over-axle piping, and exhaust tips. They offer the least performance benefits due to the minimal amount of components being replaced, and are the most cost-effective way to upgrade your vehicle’s exhaust.
Why do motorcycle exhausts split into two mufflers?
Configuration: Often, a factory four-into-two exhaust (four headers for a four-cylinder engine splitting to two mufflers) will be made aftermarket as a four-into-one system, because the exhaust can be moved almost as quickly through the less restrictive system and the excess weight of the second muffler is eliminated.
