Are There Different Types Of Performance Exhausts?
If you’ve done a bit of research on this already, you’ve probably heard or read a lot of different terms for types of exhaust. While this might sound complicated, the difference is simply how much of your original exhaust system you’re replacing.
Perhaps the most widely adopted sports exhaust, a cat-back exhaust is a performance upgrade from the catalytic converter to the end of the exhaust. This is normally about 2/3rds of the original exhaust system. You can also shop for a holden v8 UTE wagon commodore header kit for sale for any kind of exhaust issue.
When you buy a cat-back exhaust you generally get the middle pipework which sometimes includes a silencer (depending on the make and model you choose), and the rear pipework, silencers, and tailpipes.
A cat-back exhaust is normally where you start seeing noticeable performance gains from an exhaust. You’re replacing enough of the pipework and silencers that the performance gains really start adding up.
If you want to go all-in and don’t mind remapping, then a turbo-back exhaust is a highly effective performance upgrade.
It replaces the exhaust system from the turbo back to the tailpipes; a turbo-back exhaust replaces the whole factory exhaust including the original catalytic converter.
This is either going to be getting replaced with a better performing sports catalyst, or a straight-through section of pipe known as a de-cat. Both offer very similar power gains because modern sport cats are very efficient.
