Dual Magnaflow wide open mufflers with quad 3.5” exhaust tips, slightly louder and deeper than standard Borla. This upgrade option retains the large Borla resonator and replaces Borla mufflers with dual Magnaflow mufflers and quad tips. Borla is a great exhaust, but with this upgrade your back will look much better with the large aggressive oval quad tips and will sound better too! Cat-back exhaust systems refer to all of the components that exhaust gasses flow through after exiting the vehicle’s catalytic converter.

This is achieved by burning off the excess hydrocarbons which result from the extra-rich mixture required for a cold start. Slightly lean of stoichiometric, the exhaust gases from the engine contain excess oxygen, the production of NOx by the engine increases, and the efficiency of the catalyst at reducing NOx falls off rapidly. However, the conversion of HC and CO is very efficient due to the available oxygen, oxidizing to H2O and CO2. However, the efficiency of the catalyst at reducing NOx is good, and the production of NOx by the engine decreases.

Beyond these incremental advantages, there’s not much to tell cat-back and regular exhausts apart, as they are commonly made from the same types of materials in roughly the same shape. Most newer vehicles have electronic fuel injection systems, and do not require air injection systems in their exhausts. Instead, they provide a precisely controlled air-fuel mixture that quickly and continually cycles between lean and rich combustion. Depending on your make and model, cat back exhaust systems can lead to an increase in fuel economy. The engine doesn’t have to work as hard pushing exhaust gases through the piping which reduces its load and leads to higher efficiency and MPG. For car enthusiasts and performance drivers, upgrading the exhaust system of a vehicle is a no-brainer.

The purchasers are entirely responsible for informing themselves of applicable California laws and to comply with those laws. Mishimoto exhaust systems are designed for a bolt-in installation. From classic American muscle cars to the newest off-road capable rigs, we’ve got you covered. Browse our most popular performance car, truck and SUV exhaust systems to find the ultimate exhaust experience for your ride.

The products of REMUS Innovation Forschungs- und Abgasanlagen Produktions GmbH („REMUS”) are distributed worldwide. This applies equally to products approved in Austria, which are subsequently manipulated, modified, edited or otherwise interfered or changed by the respective buyer, so that it no longer has its original condition. Discover MagnaFlow’s latest evolution in performance exhaust technology. Stainless steel is the most popular choice for cat backs because it is durable and has a deep, throaty sound. But if you’re looking for something lighter weight, you can also find cat backs made out of titanium. So, when it comes time to choose the right cat back for your car, keep these three things in mind and you’ll be sure to find the perfect fit.

Since 2003, we have specialized in building BMW M-models (and Tesla) with a refined selection of industry-leading, high quality products. Our 8,000 sq/ft installation facility and shipping headquarters is located in Anaheim, California. IE’s advanced DroneTrap technology captures the pulse waves responsible for your B9 3.0T engine’s exhaust note and draws them into dual mathematically tuned resonators. The internal ports are engineered to resonate these waves against each other in a process that selectively cancels out those responsible for annoying drones.

CORSA exhaust parts, hardware and detailed instructions are included in each kit so you can get on the road as fast as possible. We hope this article has provided a thorough answer to the question of what is a catback exhaust and provided advice on how they can help improve the performance of your car. While they may not provide a big performance boost for all cars, cat-back exhausts are a simple and effective way to improve gas flow in your exhaust system beyond what stock exhausts are capable of. Catalyst poisoning occurs when the catalytic converter is exposed to exhaust containing substances that coat the working surfaces, so that they cannot contact and react with the exhaust. The most notable contaminant is lead, so vehicles equipped with catalytic converters can run only on unleaded fuel.
