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.
Straight-through, or flow-through, mufflers have perforated baffles and packing material that provides a conservative level of sound absorption while still keeping sound output moderately loud. Glasspack mufflers perform similar to resonators due to their design and lack of sound-absorbing packing material, so they tend to be louder and higher pitched. For compression-ignition (i.e., diesel) engines, the most commonly used catalytic converter is the diesel oxidation catalyst (DOC). This catalyst converts particulate matter (PM), hydrocarbons, and carbon monoxide to carbon dioxide and water. These converters often operate at 90 percent efficiency, virtually eliminating diesel odor and helping reduce visible particulates. These catalysts are ineffective for NOx, so NOx emissions from diesel engines are controlled by exhaust gas recirculation (2007 duramax egr delete kit).
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.

Each "receiving" 50mm pipe is crushed in half, squeezed next to the other and welded to the 60mm "feed" pipe. We hope you enjoyed this lighter take from 27WON and find the information helpful the next time you shop for an exhaust system.
In layman’s terms, a catback exhaust system provides a smoother, more streamlined path for exhaust gases to exit your car, allowing your engine to work more efficiently. When catalytic converters were first introduced, most vehicles used carburetors that provided a relatively rich air-fuel ratio. Oxygen (O2) levels in the exhaust stream were therefore generally insufficient for the catalytic reaction to occur efficiently.
In addition, a cat-back exhaust can also improve your car's fuel economy. So, if you're looking for a way to get more out of your car, a cat-back exhaust is a great option. We now offer Maverick cat-back exhausts in both
