In layman’s terms, a catback exhaust system provides a smoother, more streamlined path for exhaust gases to exit your car, allowing your engine to work more efficiently. When catalytic converters were first introduced, most vehicles used carburetors that provided a relatively rich air-fuel ratio. Oxygen (O2) levels in the exhaust stream were therefore generally insufficient for the catalytic reaction to occur efficiently.

And a lot of people think that gearheads mess with it just to make our cars sound louder. Another problem is that the gaskets and seals can degrade over time, resulting in leaks. These leaks can usually be fixed by replacing the relevant seals and gaskets.

Installation was super easy, and did it myself with only ramps. When IE claims 'no-drone' they really mean it - the sound is perfect! The youtube videos do not do a good job capturing the sound quality, but trust me, it's the best overall setup for your car at a reasonable price point. Enjoy a tuned and enjoyable exhaust note without any raspy leaks ruining the show. Our exhaust system assembles with our wide-width stretch clamps designed to seal and pull your exhaust connections together.

When it comes to improving your vehicle’s performance, you have two options. However, stainless still can be very expensive, as opposed to aluminized steel which is very affordable. It is also resistant to corrosion, just not to the level of stainless steel. Since there is no back pressure and the diameter is large enough, the engine will not use a lot of energy to push the exhausts out. While getting a cat-back performance exhaust system can be pricier initially, it can save on a lot of costs in the future. These exhaust pipes are usually wrapped in sound-absorbing materials, mostly fiberglass packing.

Engines fitted with regulated 3-way catalytic converters are equipped with a computerized closed-loop feedback fuel injection system using one or more oxygen sensors (also known as Lambda Sonds or sensors). Other variants combined three-way converters with carburetors equipped with feedback mixture control were used. An unregulated three-way converter features the same chemical processes but without the oxygen sensor, which meant higher NOx emissions, particularly under partial loads. These were low-cost solutions, typically used for retrofitting to older cars or for smaller, cheaper cars. Axle-back exhaust systems replace only your vehicle’s rear exhaust section, usually consisting of items behind the rear axles, like rear exhaust pipes, muffler, and exhaust tips. A&nbsp
