Outback Exhausts Give You the Ultimate in Enhanced Performance

One of the most simple recipes for success when it comes to improving your 4×4 vehicle is tuning it with the right outback exhaust. If you do so correctly – torque, horsepower and mileage will all go up as the engine will perform much more efficiently and easily. There’s a lot of science behind this claim, and it’s pretty straightforward. The gases will flow out of your vehicle in a straight-flowing and unrestricted manner, allowing your engine to “breathe” freely.

The pipes of outback exhausts shouldn’t be too big or too small. Small pipes restrict the flow of gases and big pipes make the exhaust tumble on the inside of the tubes, still not giving you a proper exhaust flow. There are a few things you need to be on the lookout for when buying outback exhausts – here’s a list of them.

First and foremost, it’s important to know that cast-iron exhaust manifolds are big, heavy and restrictive. If you ditch them for a set of aftermarket headers, you’ll free up a lot of power and you’ll reduce some of the heat the engine generates under the hood, since headers hold it in the exhaust much better than the stock manifolds. This is the nearest part of the system to the engine, so if it’s restrictive, there’s no point in having other exhaust work done. When you add a brand new aftermarket set of headers, there are a few issues you can run into.

For instance, it’s possible for the headers to be bolted onto the engine, but they won’t fit between the framerails without lifting the engine several centimeters off the engine mount first. Things like these need to be considered beforehand, else you risk being stuck paying an absurd amount for parts and spending much more time to achieve what you had in mind.

Moreover, consider getting a high-flow cat for your vehicle. It reduces a lot of the emissions your vehicle produces and you’re not doing anybody a favour by pulling it off, as it’s you and your passengers who breath the gases that are released from your vehicle most of the time. In recent times, there are high-flow cats for diesel engines as well, and the power loss from them is so insignificant that you’d be surprised to see even if it registers more than one horsepower.

When changing your stock exhaust for an aftermarket one, replace it entirely. Otherwise, you’d be only moving the most restrictive area to another part of your exhaust. Not only will replacing the exhaust completely give you better performance, it will also come as a complete compatible package which will keep the costs down.
