These look like standard mufflers with a VERY unusual side entry rear exit configuration. Notice the heat discoloration at the intersection where the split occurs.Heat discoloration shows up where there is a flow restriction. Notice also the heat discoloration just after the pipes enter the silencers. It is AMAZING the engine makes the power it does through this congestion.

That’s why we carry a wide lineup of sport exhaust systems, from individual pieces to full kits, made by some of the best manufacturers in the industry. We take exhaust so seriously that we also make our own branded exhaust systems in our own facility. We use 304 stainless steel for extra durability and life, and ensure every component is forged to fit your vehicle. Cat-back exhaust systems have more efficient gas flow, yielding increased engine performance, thanks to their larger exhaust tubes and mandrel bends. As a result, your car will be able to breathe better and produce more power.

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.

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.

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.
