Because the engine won’t generate as much fumes and doesn’t need to work as hard to eliminate or minimize the fumes, your car will run better, saving you mileage. A benefit like this will improve the longevity of your car and even save you money at the gas pump. At Bradley’s Auto Service in Red Bank, NJ, we can build a completely custom exhaust system for your vehicle, including cat-backs. We will work with you to create your exhaust exactly the way you want it, with any combination of look, sound, feel, power, or muffler at your fingertips.
The difference is that the dual exhaust system has two exhaust systems on one vehicle. Meaning, when modifying your exhaust, never start from the front of your turbocharged vehicle with a downpipe or with headers on your naturally-aspirated platform, you will create a bottleneck in the flow. By starting with a cat-back first, your exhaust gases will flow more freely if the rest of your system is stock.
Considering cat-back exhausts replace more restrictions, they typically offer increased performance and noise compared to axle-back systems
