Generally speaking, it&apos;s always a good idea to get a tune for your vehicle when fitting a performance exhaust. If you&apos;re fitting a high flow catalytic converter, alongside headers or a dump pipe you will need to get a tune, as your vehicle will show engine codes with a scanner of the dash of the car. This, is a result of excessive flow from the motor which needs to be regulated for efficiency and performance. If you don&apos;t do get a tune done you might experience some issues related to excessive fuel usage or miss fires.

A catback exhaust system is a relatively simple power modification that will free up your exhaust gas flow and produce an engine note that is louder than your stock system. A catback exhaust is usually made up of a rear-pipe, a resonator and a muffler, but depending on the make and model, it can also include a mid-pipe, X-pipe, H-pipe or a Y-pipe.&#xA0;Adding an aftermarket catback exhaust provides several benefits, the first of which is more power. Aftermarket exhaust systems are designed to be freer flowing than your stock exhaust, usually incorporating larger diameter piping and higher-grade mandrel bent tubing for a more laminar flow. These changes can result in a reduced level of back pressure at the engine manifold, which means the engine can breathe a little easier and release more horsepower and torque. How much horsepower is gained depends highly on the design of your factory exhaust system and the quality of the catalytic converters in front of it. If the stock catalytic converters are fairly restrictive, then less power can be gained from a cat back exhaust system. If the stock cat&#x2019;s can flow a large amount of exhaust gas with creating too much restriction, then a cat back exhaust system should offer a nice increase in power.&#xA0;An increase in fuel economy can often be experienced after installing a cat back exhaust system. This is the result of the engine not have to work as hard pushing exhaust gases through the piping.

If you&#x2019;re running a turbocharged car, long tube headers aren&#x2019;t usually feasible or practical, so these cars will usually have shorty headers that feed right into the hot-side inlet of the turbo. Otherwise, long-tube headers are generally considered to be the best for reducing back pressure as much as possible, and therefore the best for scavenging &#x2014; this is despite the fact that they actually technically flow less than shorty headers generally do, but after the section above, we have a good understanding of why that is.Another advantage with long-tube headers is that they not only give solid peak power numbers, but help to raise horsepower and torque in the low and mid-range of the RPM band, giving you more useable power down where you usually need it. This makes for a more fun drive day to day, as you&#x2019;re rarely able to enjoy wide-open throttle out to redline out on the street.The disadvantage comes in the form of packaging. Some cars are worse than others, but it can be difficult to route that big cluster of tubes out of the way of motor mounts, the firewall, the transmission, and still have ground clearance for them afterwards.We always recommend speaking to your tuner before getting headers fitted. This way, they can optimise your vehicle to your request with the right parts.Quick Summary:Long tube headers build a ton of power in the mid to high RPM range. They are the best option for high-rev vehicles, and track terrors. But they aren&#x2019;t necessarily street legal, depending on emission standards. And usually, long tube headers are difficult to install. All the extra room they need inside the engine compartment may call for some costly reconfiguration.Short tube headers perform best in the idle to mid-RPM range. This makes them the perfect headers for vehicles that rely on low-RPM power, like a daily commuter or a work pickup that sees a lot of towing and hauling
