Most end up reducing performance and adding weight, or worse yet – adding cost and doing nothing at all.

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.
Glasspack mufflers do not have extra sound-absorbing material. So, in order to absorb sound, they use the glass layer and packing. But if you are making your order on partcatalog.com, you can always inquire about the recommended tube diameter for your exhaust system by providing your make and model. This can lead to a significant decrease in torque and horsepower as well as rpm.
By running pipes from the catalytic converter to the muffler and from the muffler to the exhaust tip, cat back exhaust systems improve exhaust gas flow, providing small performance boosts. However, your performance gains may be limited if your catalytic converter restricts gas flow, as a catback exhaust system is installed ‘downstream’ of the converter. Header-back systems are increasingly rare, namely because of modern emissions systems. Since removing your vehicle’s factory emissions components is highly illegal, the previous two options are more common. However, header-back systems are still available for some older, pre-emissions applications. In these cases, header-back systems offer more performance and volume than cat-back or axle-back systems
