You also need to be careful when tightening the bolts on the cat back. Over-tightening can damage the system, so just make sure they're tight enough to hold everything in place. It's important to make sure that the cat back is properly aligned with the exhaust pipe. If it's not, you could end up with an inefficient or even dangerous exhaust system. Competitors often rely on generic silencers or gimmicks that claim to cut out drone without any real knowledge or development involved.
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.
