A cat-back exhaust system is a modification in the exhaust pipe to improve airflow. The system runs from the tip of the exhaust to the catalytic part of the system. The cat-back system comprises a pipe connecting the muffler to the catalytic converter, and the exhaust tip.
What’s the difference between Catback and regular exhaust?
Cat-backs generally yield increases in performance, due to the more efficient flow of exhaust through upgraded parts like larger diameter tubing and better flowing mufflers, as well as improved sound and reduced weight.
Is a cat back exhaust loud?
Straight through cat-back systems have mufflers of minimal size with fewer baffles. This creates a louder sound and a low amount of restriction.
Does a cat back exhaust sound better?
Cat-back exhaust replaces your stock muffler with one that’s less restrictive. This means the sound from combustion will still be suppressed, but not so much – resulting in a more aggressive and louder sound.

In general, expect a 2-5 percent increase in torque, horsepower, and fuel mileage. But, of course, the amount of power increase you’ll experience depends on how restrictive your stock exhaust is.
Is a Catback exhaust worth it?
The cat-back system improves airflow, which means the engine doesn’t work as hard to eliminate exhaust fumes. The reduced resistance minimizes the load on the engine, which leads to less fuel consumption. That said, the vehicle miles per gallon (MPG) or fuel economy increases in freeways and city roads.
Why do they call it a cat back?
The two most popular exhaust modifications are axle-backs and catbacks. They get their name because they replace the exhaust pipes from the axle, back. The catback replaces your exhaust from the catalytic converters back, including the mufflers.
Is a Catback exhaust louder than a muffler delete?
A cat back will smell worse than stock, and a muffler delete will make the car louder.
Are cat back exhaust louder than Axleback?
The catback exhaust, by definition, includes the catalytic converter. The big advantage of an axleback exhaust setup is louder exhaust noise (depending on the type of muffler) and significantly reduced back pressure.
How much mpg does a cat back exhaust add?
Bottom Line: Adding an after-market performance muffler or exhaust system will improve engine efficiency from 2-10%. Improvements in efficiency can be used to either increase horsepower or improve fuel economy. Whether this efficiency is used to go faster or to get better fuel economy is up to you and your foot!.
Are cat back exhaust systems legal?
Are They Legal? Catback exhaust systems are completely legal in the State of California because the modification starts after the catalytic converter and does not affect any of the emissions control components of your vehicle.

Which exhaust system is the loudest?
The loudest possible is the absence of any exhaust manifold, surrounded by a rectangular resonant chamber around the exhaust port. Next is the absence of any exhaust manifold but with no resonant chamber. Next is short headers with no other exhaust system.
Is Cat-Back Same with muffler?
Cat-back exhaust refers to any part of the exhaust system that’s behind the catalytic converter.

Do Catback exhausts have mufflers?
Cat-back exhaust systems will include any pipes that run from the catalytic converter to the muffler, the muffler itself, any pipes that may run from the muffler to the exhaust tips, and the exhaust tips themselves.
