INCREASING POWER & DESIGNING SOUND
The axle-back, header-back and cat-back exhaust.
We at VOS PERFORMANCE believe that a complete an efficient performance upgrade can only be achieved with a building/rebuilding the cars exhaust system. Here are some basic details in order to fully understand the correlation between the different exhaust parts.
An axle-back exhaust system consists of all the elements from the exhaust tip to the rear axle. While cat-back and header-back exhaust systems may deliver more power, this kind of system is more often than not less expensive than the other two. An axle-back that is well designed is more powerful than the stock one and it’s a lot easier to install than the cat-back or header-back one.
A header-back exhaust system replaces all the components from the tailpipes to the header collector. Because it replaces all the components, it allows you to make the diameter of the entire exhaust system larger, which will let more exhaust gas flow through it. These kinds of systems, however, are more expensive and a lot harder to install.
A cat-back exhaust system will replace components back from the catalytic converter. They usually come with a tailpipe and muffler but based on the model and make they could also include a Y-pipe, H-pipe, X-pipe or a mid-pipe. These are one of the most popular exhaust systems.
