Namely, it replaces the rear axle-back and tips and then a portion of what we refer to as the mid-pipes. This system is emissions friendly and doesn’t require any tuning. In New Jersey, vehicles must pass emissions testing to ensure they meet environmental standards. Since cat-back exhaust systems do not modify the catalytic converter or engine management system, they generally do not affect a vehicle’s ability to pass emissions testing.

At Euro Car Parts, we have exhaust parts to help you do just that. It is important to note that the fuel saving will be more noticeable when traveling at freeway speeds than city driving, but if you spend a lot of your day on the road, you’ll likely notice the difference. View our technical tips to help you install, learn about and maintain your exhaust system the right way.

The first widespread introduction of catalytic converters was in the United States automobile market. The exhaust system is crucial to a car’s performance, especially the catalytic converter which can go bad if it’s overworked. A stock exhaust system strives to minimize the car’s materials while maximizing space. This means that the exhaust system’s performance can suffer, having to work harder with less horsepower.

There are loads of options, all offering different benefits, and the amount of research you do can quickly turn to frustration when you realise the minuscule differences between the many options. OE-quality exhaust products engineered for today's medium-duty and heavy-duty vehicles. The single 60mm is split into twin 50mm pipes to the twin silencers.

As a result, the glass pack mufflers end up producing sounds that are more aggressive and louder than the straight-through muffler. This is a little bit different from most original exhaust systems. Today we’ll focus on the cat-back exhaust systems and what makes them stand out. There are the header-back, turbo-back, axle-back and cat-back systems.

Federal Catalytic Converters are not legal for sale, installation or use in the state of California. It should be noted that a split system will often provide an aggressive noise increase, and some designs will split the two pipes to opposite sides of the vehicle. If you are looking to save a little money but still get most of the benefits of a cat back exhaust system, however, aluminized steel may be the way to go. Made from traditional steel that’s been coated on all sides with aluminum-silicon alloy, these systems are very strong thanks to the metallurgical bond which still provides a level of corrosion resistance. While the aluminum coating reflects heat well, the steel can corrode if the aluminum layer is chipped or scraped off. Most cat-back systems will come in either an aluminized or stainless steel version.

Because the success of a catback exhaust system&nbsp
