Landcruiser 79 Series Single 4" Stainless Exhaust System
PLEASE NOTE:
If you have an existing coil conversion on your vehicle you will require in shop fitting of our exhaust system. Please contact our team at admin@gslfab.com.au for booking. If you’re interested in a coil conversion for your vehicle please let our team know.
This system can be beneficial for Landcruiser's fitted with under-tray mods - such as toolboxes and auxiliary water tanks. If practicality is your number one concern, than this exhaust is a prime candidate for your vehicle.
Our 4" single exhaust system, made for the Toyota 79 series Landcruiser. The twin's little brother, is no runt of the litter, you can still expect the quality GSL sound you've come to know with the single exit 4" stainless steel system. One of the sexiest systems on the market; twin exit, brushed 304 stainless steel, 4 inch pipe, handmade and tig welded in shop. Which means our exhaust systems are completely Australian Made.Â

Adventure proof
If you plan on getting a cruiser, chances are you plan on giving it a bit of a hammering, whether it be off-roading, camping, beach driving, Hill climbing or more. We’re exactly the same, and because of this, we strive to make sure our exhausts are built to withstand the toughest adventures. High quality 304 grade 4’’ stainless steel, sturdy custom folded bracketry, and top quality welding work.

Hand made by true 4x4 lovers
At GSL, all of our piped systems (exhausts, engine upgrades etc.) are made completely by hand. With over 10 years of perfecting and adjusting exhaust systems, one bend at a time, our reputation for outstanding quality products speaks for itself. Not to mention, it looks fantastic! All of our products are Australian made and sourced, so you’ll also be supporting local Aussie suppliers.


TURBO BACKÂ
The ‘turbo back’ systems are great for pre DPF models (pre-2017).
They give the nicest note, and best performance gain of all exhaust types, however more recent models are legally required to have a DPF in place. This variant removes the DPF entirely and in most areas, is an illegal modification - thereby voiding any warranty’s on the vehicle. This is an option for off-road and track use only.
The system starts with a 5 inch dump, moving into a 4 inch CAT, a 4 inch muffler section, and finishing off with a 4 inch tail.




ELITE DPF SYSTEM
Australian made upgraded DPF (Diesel Particulate Filter). The main reason for this mod is to give you the V8 note that standard DPF models are lacking. Being a high flow, this eliminates the bottle-necking issue with the standard DPF’s, and assures consistent power with no drawbacks.
This option is great for everyday use, keeping your vehicle compliant with vehicle emission standard.
The system starts with a 5 inch dump, moving into a 4 inch Elite DPF Section a 4 inch muffler section, and finishing off with a 4 inch tail.
The Elite DPF system is an in house only, we cannot post this exhaust system as it does require remapping by GSL.Â
GSL High-flow Elite DPF System
The Elite DPF System is our own proprietary Active DPF solution that allows better flow, and can handle higher temps than factory. This system however is not available for delivery, and can only be installed in our store, or via one of the certified dealers below
- Cutlers Diesel Performance
- G&L Motor Repairs & Performance
We also do not sell this in sections, but only as a full exhaust system - front to back. Our Elite DPF will also require a remap to setup the burn rate, and other settings to suit your vehicle.Â

DPF BACK
This system utilises the standard DPF, while still delivering the great note of our exhausts. If you’re chasing sound over performance, then this is the perfect exhaust. From the back it’ll look just as good, so you don’t miss out on aesthetics either!
This option is great for everyday use, as it’s a little quieter and keeps your vehicle compliant with vehicle emission standards.
The system starts with a Standard DPF to 4 inch adapter section, moving into a 4 inch CAT, a 4 inch muffler section, and finishing off with a 4 inch tail.
