Toyota Diesel Exhaust System Upgrades

Three Reasons To Upgrade Your Exhaust System

Upgrading your Toyota diesel engine’s standard exhaust system to an aftermarket performance system can result in a significant improvement in power and torque outputs, fuel economy, and overall performance. At Just Autos, we offer a wide selection of exhaust systems that cater to various sound requirements and desired notes for your vehicle. Our exhaust systems come equipped with high-flow catalytic converters and mufflers to ensure efficient exhaust flow while maintaining a mild note, with minimal drone when needed.

All our systems are made from 409-grade stainless steel, which is a highly pliable metal capable of withstanding extreme temperature changes commonly experienced by exhaust systems, thus preventing cracking. The muffler casings are made from 304-grade stainless steel, while the internal perforated tube is stainless steel with a stainless-steel wool wrapped around it, protecting the fiberglass packing in the muffler.

Better Fuel Economy

Standard exhaust systems are designed for the ‘de-tuned’ factory engine, while aftermarket performance exhaust systems can result in better fuel economy.

Improved Airflow

Most factory-standard exhausts contain distinct bent sections of pipe, which decrease the diameter of the exhaust and can inhibit exhausts gases passing through.

More Power and Torque

The right exhaust system can make a huge difference to power. Upgrading to a performance exhaust system will allow your engine to perform better, resulting in more power and torque.

Diesel Exhaust Upgrade FAQs

Prepare for Your Performance Exhaust System

We fit it aftermarket to improve the flow of the gasses expelled from the turbocharger assembly when tuning. Running higher boost pressures and increased fuelling will increase temperatures inside the exhaust manifold and turbocharger assembly. Having a larger free-flowing system of exhaust will help in aiding the removal of this extra heat when tuning a diesel vehicle.

When tuning a wide majority of vehicles an aftermarket exhaust is required to tune the vehicle efficiently, the factory system of exhaust has restrictive mufflers and bends which can decrease the exhaust flow and restrict the amount of torque and power we can achieve efficiently.

Most common rail vehicles require to be tuned once having an aftermarket exhaust fitted to fully utilise the gains that can be achieved, in some cases when fitting an aftermarket exhaust you can have issues with sending your vehicle into limp mode caused by a freeing flowing exhaust which causes the turbo to spike above your factory ECU’s desired boost limit.

Depending on the model of vehicle most exhaust upgrades alone can see up to a 5% increase in power and torque.

Many factors come into play when it comes to making a great system of exhaust, high flow mufflers and mandrel bends will help with exhaust flow, 409 stainless exhaust will help with overcoming rust holes developing in your exhaust system and is a very pliable metal that accommodates the extreme change in temperature seen in it. This prevents cracking.

Most systems of exhaust will discolour over time, some will even develop surface rust. We recommend washing the full under carriage of your vehicle down regularly to prevent surface rust developing and getting the best life out of your exhaust system.

An exhaust alone will achieve a small % gain in torque and power, but when coupled with a Just Autos custom ECU remap, you can expect a sizable % gain over factory figures.

The 79 series Landcruiser exhaust can come in many sizes but 3” or 4” are the most popular systems, saying that 3” and 4” will still see the same results for power when using a factory turbo but will produce vastly different sounds when under load. When fitting an upgraded turbo from G Turbo a 4” exhaust is required to be port matched with the rear exhaust outlet of most G turbos.

Stainless steel exhausts will provide a longer lasting exhaust system while also preventing the system from rusting out over a long period of time, we recommend fitting a stainless exhaust system when touring to prevent failure while out and about

Most diesel vehicles require mufflers to comply with ADR standards.

Cat back exhaust are quite cheap because they leave the restrictive factory catalytic converter and dump pipe in place but replace the rest of the system, re recommend replacing the exhaust from the turbo back to achieve a more efficient exhaust flow.

Stainless exhaust can discolour and develop surface rust over time, we recommend cleaning down your exhaust regularly to prevent this from happening however if this does occur a good quality metal polish and stainless-steel wool will clean this right up.
