One main reason for choosing to remain with a stock system is because it comes already installed on your vehicle. You should know the difference between a dual exhaust and a dual exit exhaust system. But it is easy to mistake a dual exit exhaust for a dual exhaust system. The materials are often 304 stainless steel or aluminized steel. The stainless steel is usually coated in special metals that make it corrosion-resistant. This means there will be a reduction in the amount of load on the engine, leading to higher mpg and fuel efficiency.

The only difference is that it features straight perforated pipes. The original exhaust systems focus more on just reducing the sound and not shaping it to give it that desired deep growl. One function shared with both the axle-back and the cat-back exhaust systems are shaping your vehicle’s tone.

We want to make sure the part fits your specific vehicle so we need a little more information from you. You can find out by inspecting the emissions sticker that is located in your engine compartment.

Our design concept is to provide a sporty and authentic exhaust note, while improving performance, and enhancing the visual styling of your vehicle. Each product is carefully developed, and then expertly crafted by our own factory. The whole reason I decided on an IE cat back vs mbrp or AWE was the craftsmanship. However I do live in warm and sunny south Florida so I know it will only see tons of rain but never salt or snow unless it’s an impromptu trip. I love the lil burble crack when going down in rpm and down ship. I wish it were a little louder but if that we my main goal I’d have just gutted cats n resonators n left stock mufflers.

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
