2015 Pre-DPF Dual Cab Models:

LandCruiser 79 Series Single 4" Stainless Steel Exhaust System
The Single 4" Stainless Steel Exhaust System delivers the signature GSL sound and quality that LandCruiser owners have come to expect. Designed and manufactured in-house from premium 304 stainless steel, each system is hand-built and TIG welded to ensure exceptional durability, performance, and craftsmanship.
Built for those who want a strong V8 note, improved exhaust flow, and a premium finish, this system offers the perfect balance of performance, sound, and everyday drivability. As with all GSL Fab exhaust systems, it is proudly Australian Made
Turbo Back SystemOur Turbo Back Exhaust System is available for both Pre-DPF and DPF-equipped vehicles and delivers the most noticeable improvement in sound and performance. By replacing the factory exhaust components from the turbocharger rearward, this system provides the true V8 exhaust note that many owners are chasing.
For DPF-equipped vehicles, this option removes the Diesel Particulate Filter (DPF). Please note that DPF removal may not be compliant with road-use regulations in your area and may affect your vehicle warranty. These systems are intended for off-road and competition use only where permitted by law.
System configuration:
- Cast stainless steel 5" dump pipe
- 4" catalytic converter
- 4" muffler section
- 4" tailpipe
The DPF Back Exhaust System retains the factory DPF while enhancing exhaust tone and maintaining a clean, premium appearance. This option is ideal for owners who are looking to improve sound and aesthetics without compromising emissions compliance.
Designed for everyday driving, the DPF Back system offers a refined exhaust note that is quieter than the Turbo Back option while still delivering the quality sound and finish GSL Fab is known for.
System configuration:
- Factory DPF to 4" adapter section
- 4" catalytic converter
- 4" muffler section
- 4" tailpipe

Elite DPF System -No Longer Available
Our Elite DPF System is an Australian-made upgraded Diesel Particulate Filter solution designed specifically for LandCruiser owners who want to enhance exhaust sound while maintaining emissions compliance.
Featuring a high-flow DPF design, this system reduces the restriction commonly associated with the factory DPF, helping to improve exhaust flow while delivering the deeper V8 note that many standard DPF-equipped vehicles lack. The result is a more enjoyable driving experience with consistent performance and no compromise to everyday usability.
This option is ideal for daily-driven vehicles and maintains compliance with applicable vehicle emissions standards.
System Configuration:
- 5" dump pipe
- 4" Elite DPF section
- 4" muffler section
- 4" tailpipe
Please Note:
The Elite DPF System is available for in-house installation only. This system requires ECU remapping, which is completed by GSL Fab during the installation process. Due to these requirements, this exhaust system is not available for freight.
