A dual exit on the other hand, is just a single exhaust system but with two exhaust tips. This is because, with a cat-back exhaust system, you will experience a significant increase in your fuel economy. The tone provided by different cat-back exhaust systems varies from one system to another.

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.

It typically includes a rear pipe, resonator, and muffler that all attach after the last catalytic converter. The turbo-back system is the most complete system you can buy. It replaces all of the components that the previous two systems that we’ve talked about and also upgrades the downpipe. The downpipe is the first piece of exhaust piping that comes after the turbocharger and it also houses the catalytic converters on all L15 powered 1.5T Civics and Integras. From a sound and performance perspective, you’re going to get the most of both compared to the other two versions mentioned before.

Let’s look at the top ten reasons why a cat back exhaust system may be right for you. While a cat-back exhaust system includes all components from the catalytic converter to the exhaust tips, an axle-back system only replaces parts from the rear axle to the tips. Axle-back systems are generally easier to install and less expensive but offer more limited performance improvements and sound changes compared to cat-back systems. All our performance exhaust systems are designed with you in mind, and we cater to an ever-expanding range of vehicles. We believe in continuous evolution, and our research &amp
