How to Choose Aftermarket Mazda BT50 Exhaust

If having an adventurous trip off-roading in the wild is your thing then a vehicle like the Mazda BT50 is definitely a vehicle you would enjoy driving. This 4×4 comes with a spacious interior and it is excellent for off-roading since it is an extremely easy to drive a vehicle even on challenging terrain. Mazda vehicles are in general easy to drive thanks to their unique approach to making vehicles as well as engines. Mazda utilises one of their own technologies called “SKYACTIV” which helps maximise efficiency and driving dynamics.

Mazdas are one of the more reliable vehicles you’ll find today and they are also some of the safest thanks to Mazdas own core safety technologies such as ITS (Intelligent Transport System). You can find a Mazda BT50 well equipped with today’s newest entertainment technology as well as being made with comfort in mind. But something that a lot of Mazda owners seem to be after is even greater performance which you can have if you replace your existing BT50 exhaust with a new upgrade.

Types of BT50 Exhaust Upgrades


There are four different upgrades you can go for with each one having a different effect and taking a different time frame to be installed. Take an axle-back BT50 exhaust upgrade for example. It is one of the least invasive exhaust upgrades since it only replaces the components from the back axle to the exhaust tip. This not only takes very little time to be installed but it is also the most affordable option. Don’t expect big performance improvements from an axle-back exhaust upgrade since it only affects a small portion of an otherwise complex system.


A cat-back upgrade is one that will replace every component from the catalytic converter back to the exhaust tip. The catalytic converter is a component that is meant to reduce harmful emissions but it puts a lot of restrictions while keeping tabs on air pollution. This is why a car-back exhaust upgrade takes more time to be installed but it will offer a much bigger difference in performance.



If you want to completely replace your Mazda’s exhaust system then you should go for a header-back upgrade. The header is the exhaust component that comes in contact with the engine. Because of this, you will get the biggest jump in performance with a header-back upgrade but you’ll also spend the most amount of money and time installing it since it’s essentially installing a brand new exhaust system.


If your BT50 is turbocharged, (most of them are) then you should go for a turbo-back BT50 exhaust upgrade. This upgrade will only make sense if you have a turbocharged engine and it will provide the most cost-efficient performance improvement and the least invasive one too.

Mandrel Bends

Other Factors to Consider


There are two types of ways an aftermarket exhaust system’s curves can be made, either by crush bending or mandrel bending them. Crush bent exhaust systems are those that have wrinkles where the piping makes a turn. These are more affordable but also more restrictive when it comes to airflow. With a mandrel-bent Mazda BT 50 exhaust system, you get all-around smooth piping even at sharp turns. This costs more but doesn’t put restrictions on exhaust gasses and fumes. This also makes for less pressure in the systems and thus making the engine work more efficiently


You can go for either a steel or aluminium BT50 exhaust system. A BT50 exhaust made of steel will be much stronger but it will also weigh more which can affect fuel consumption negatively. While an aluminium exhaust system will make for a more heat resistant and lightweight system which is also going to be naturally corrosive resistant. If you want your steel exhaust system to be anti-corrosive then you’ll need to have it coated with a special layer to keep it safe from corrosion.



When it comes to the configuration of an exhaust system there are also two options you can go for, either X or H-pipes. An H-pipe system is one that has a single piece of angled pipe that is connected at the middle of a dual exhaust configuration. This type of configuration allows exhaust gasses to exit through both sides of the system which helps reduce exhaust noise quite noticeably.

An X-pipe configuration is the better version of an H-pipe configuration. While its older counterpart reduces noise effectively, an X-pipe configuration improves power throughout your vehicle’s rev range. This is thanks to the smooth transition of the two pipes into each other with no pipe in the middle adding one more step to the whole process. This results in a fully equalised pressure making your BT50 even more powerful and even more efficient. Remember X-pipe configurations are best for V-type engines while an H-pipe configuration is best for big V8 block engines.
