Walker is your one-stop exhaust shop, offering a full line of mufflers, pipes, hardware and accessories. Cat to Y pipe intersection showing after cat O2 sensor location. This qualifies as one of the STRANGEST stock exhaust parts I have seen. For some reason Toyota/Lexus decided to weld a straight section of 60mm pipe to the cat outlet flange, angle cut it, weld a 50mm pipe pipe that has its last couple of inches expanded to 60mm and match angle cut. Also note the O2 placement is in the 50mm sections of the Y pipe where the sensor tip takes up a good portion of the available flow area.
An upstream air injection point, ahead of the catalytic converter, is also sometimes present to provide additional oxygen only during the engine warm up period. This causes unburned fuel to ignite in the exhaust tract, thereby preventing it reaching the catalytic converter at all. This technique reduces the engine runtime needed for the catalytic converter to reach its "light-off" or operating temperature. Many vehicles have a close-coupled catalytic converter located near the engine's exhaust manifold. The converter heats up quickly, due to its exposure to the very hot exhaust gases, enabling it to reduce undesirable emissions during the engine warm-up period.
These two work together to offer better flow and allow the system to breathe better. We are one of few brands that own our factory thus enabling us full control over the manufacturing process, selection of raw materials, and construction techniques. Install your IE catback without any permanent modifications or installation hassles. The installation process is straightforward and accomplished with standard mechanic tools.
A cat-back exhaust system is one of the best ways to improve your car's performance. It replaces the stock cat-back exhaust system and gives your car a more aggressive sound. Perhaps the most significant benefit is the increased power that it can provide.
This modification includes the pipes, muffler, and sometimes the resonator. The term "cat-back" itself signifies that everything behind the vehicle’s catalytic converter is being upgraded or replaced. Milltek's Sport Catback Exhaust Systems are designed to compensate for the sound reducing qualities from the particulate filter and significantly improve the sound aesthetic of the exhaust system.
It is important to note, however, that going too large may cause a dip in performance when gases pile up and exit the system slower resulting in torque, rpm, and horsepower loss. After the emissions are channeled out from the cylinders by the exhaust manifold, they are deposited into different catalytic converters. The IE Catback Exhaust System for your Audi B9/B9.5 inch exhaust hanger S4 incorporates our in-house engineered DroneTrap technology to deliver a truly aggressive exhaust note without any annoying drone or rasp. Engineered with cutting-edge design features, including mandrel-bent stainless steel, TIG welding, multi-point reinforcements, and oversized quad tips. A catback exhaust system is a type of aftermarket exhaust system that replaces the muffler and tailpipe of a vehicle. It is called a "catback" system because it starts at the catalytic converter, which is located in the middle of the...
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 DroneTrap system is wrapped up in our stamped multi-wall resonator that reinforces the housing inside and out. This high level of manufacturing protects the resonator from warping or splitting at the welds under exhaust movement.

To make a very long story short so far so good I’m happy with the product. I had 1 dinged tip out of the 4 that prob happened during shipping n y’all already have a new replacement tip on the way so customer service is great as well. Only thing I would change as previously stated would be a little more noise but again that wasn’t my main goal to being with. Hats off to what y’all do and please make more B9 Audi S4 parts n I’ll happily buy them. I regret not buying the IE intake but hey sometimes we all make poor decisions lol. Every vehicle-specific CORSA product is engineered and designed to match the unique properties of the vehicle it is designed for to deliver perfect fitment and performance.
You can also add other upgrades to give your Charger an extra performance boost. Visit the AmericanMuscle headers and exhaust accessories pages to find parts that fit your new cat back system. Mishimoto offers a wide selection of exhaust systems, including cat-back exhausts, performance exhaust systems, and aftermarket exhaust options, designed to enhance your vehicle's performance, sound, and style. Our exhaust systems are engineered with precision and constructed using high-quality materials to deliver improved exhaust flow, increased horsepower, and an enhanced driving experience. Enhance the sound and performance of your Subaru with our premium cat back exhaust systems. Designed to replace the factory exhaust system from the catalytic converter rearward, these cat back exhausts offer a deeper, more aggressive exhaust note while reducing restriction for improved airflow.
Glasspack mufflers do not have extra sound-absorbing material. So, in order to absorb sound, they use the glass layer and packing. But if you are making your order on partcatalog.com, you can always inquire about the recommended tube diameter for your exhaust system by providing your make and model. This can lead to a significant decrease in torque and horsepower as well as rpm.
Installation was easy, and the craftsmanship and welds are very high quality. Mishimoto exhausts are constructed of large diameter mandrel-bent pipes for maximum flow. Mishimoto exhausts are perfectly engineered to provide an aggressively rich tone with no annoying highway drone. In general, though, you can expect to pay anywhere from $1000 upwards for a good cat back exhaust system. That may seem like a lot of money, but keep in mind that a cat back exhaust can provide a significant boost to your car's performance and help it to stand out from the crowd. Typically a cat-back exhaust upgrade can be swapped with the original exhaust without any modifications.
