Manta Exhaust Systems for the Mazda BT-50
Manta lists BT-50 systems by generation and emissions equipment. The 3.2L CRD from October 2011 to 2016 has no DPF and is offered as a 3 inch turbo-back with the option to leave out the diesel catalytic converter for off-road use. The October 2016 to 2021 dual cab with DPF is offered as a DPF-back or turbo-back, and Manta says the system uses factory mounts with a flex bellow to protect against cracking.
What a 3 Inch BT-50 Exhaust Changes
Manta says a 3 inch exhaust has a three-fold effect: it spools the turbo faster, derestricts the exhaust for more power and torque, and reduces exhaust gas temperature so the engine runs cooler. The DPF-back versions use a small 4 inch round hotdog resonator for a slight increase over factory noise, because the factory DPF already mutes the note. Results depend on the vehicle and tune, so treat figures as indicative.
DPF-Back or Turbo-Back for a BT-50?
A DPF-back keeps the factory filter and replaces the pipework behind it. A turbo-back replaces the entire exhaust, needs ECU recalibration and is intended by Manta for off-road or race use. Whether a modification is acceptable on the road depends on the vehicle, its installation and state or territory rules. Our D-Max and BT-50 exhaust guide compares options, and our exhaust fitting page can arrange professional fitting. Add flex bellows and exhaust gaskets as needed, and confirm model year and DPF status before ordering.
Materials, Warranty and Fitting
BT-50 systems are offered in aluminised or stainless steel, and stainless generally resists corrosion for longer in wet, salty or off-road conditions. Warranty terms vary by material and part number, so check the listing. Replace worn exhaust rubbers and exhaust hangers during installation, and see our delivery information page for shipping details.
