Aftermarket exhaust kits for 4Runners are one of the easiest upgrades and 4Runner mods to install. They also offer a world of difference in power performance. 

The exhaust mechanism can be an afterthought for many Toyota 4Runner, Tacoma and Tundra owners. There’s a common assumption that as long as the exhaust isn’t blocked, it’s doing its job just fine. Actually, the exhaust system is crucial to your 4Runner Engine Performance. It’s not just a pipe that lets the waste gasses out of your car; it’s an essential step to the combustion process.

With a great performance exhaust assembly from TRD, your Toyota 4Runner, Tacoma and Tundra will run better and be more efficient. Get the most out of your 4Runner with aftermarket exhaust from TRD.

Wait, TRD Doesn’t make an exhaust for the 5th Gen 4Runner?

No, they don’t. What sucks about some of the TRD options on a 4Runner is that there aren’t that many. There is no 5th Gen 4Runner TRD Supercharger and there is no TRD Catback Exhaust system. TRD (Toyota Racing Development) makes an exhaust system for the newer Tundra and the 2017 Tacoma but not for the 4Runner?

There are however many other aftermarket alternatives to the TRD line of exhaust systems. Like the 5th Gen 4Runner Magnaflow Exhaust (Cat-Back), which in my honest opinion, kicks ass. As well as the Borla Catback Exhaust and the Flowmaster Catback Exhaust system. We have read good and bad things about all of them, it’s on you to use your best judgment in deciding which exhaust system to rock on your 4Runner.

Reduction in Performance from Factory Exhaust Systems

Most modern engines use a four-stroke process. The last step of the combustion process is the removal of the waste gasses from the engine. When the waste gasses aren’t removed efficiently, this can cause back pressure, which reduces the power output of the entire engine. Therefore it is essential that the exhaust method for the car be able to get out the burned gasses so that the rest of the combustion process can happen effectively.

The method of the exhaust portion of the combustion process happens this way. At the beginning of the exhaust stroke, the exhaust valve opens. The piston pushes the gasses out. Ideally, there should be no resistance to this step, and the piston should be able to push the gasses out of the cylinder easily. If there is already pressure there and the piston has to push against any resistance, energy is wasted.

CAI (Cold Air Intake) System to Increase Performance

This is known as back pressure, and it causes inefficiency on the back end of your engine operation.  To get the most out of your exhaust system, whether it is a TRD exhaust system, Borla Exhaust System, Gibson Exhaust system or a Magnaflow Exhaust system, you want to install a CAI. A CAI (Cold Air Intake) system opens up the airflow even more. There are many options when it comes to aftermarket CAI systems on the 5th Gen 4Runner, but we highly recommend the TRD CAI (Cold Air Intake) and the AFE CAI system. Both of these are fantastic CAI’s for 5th Gen 4Runners. 

How an Exhaust System should Act (Aftermarket Exhaust Systems)

The goal of the exhaust system is to move the gasses out of the engine and away from the car as quickly and effectively as possible. However, the exhaust system can’t just be a tube leading away from the car. The gasses have to go through a catalytic converter and a muffler before they can be vented. This makes the car run quieter and also helps to reduce the greenhouse gasses that are emitted from the car. This is why the entire exhaust system is so important: to maximize efficiency and also give you a quiet, high-performance exhaust system.

The TRD aftermarket exhaust products combined with an Aftermarket TRD Air Filter do exactly that for the car. They are engineered to provide maximum performance and minimum back pressure. They even increase your acceleration by adding low-end and mid-range torque and improving your horsepower. TRD aftermarket exhaust systems are legal in all 50 states and lower the tone of the muffler to a deeper, more pleasant sound. Even the outer appearance is better: a dual wall construction keeps the bright, stainless steel outside from being discolored by the heat inside.
