Before we talk about why an upgrade is important, you need to understand what an exhaust system does in the first place. It’s quite simple: the exhaust system is responsible for channeling exhaust gasses out of your car. Several components are involved in this process, from the catalytic converter to the muffler. With that taken care of, why should you upgrade your exhaust system?
More Power
Who doesn’t want a bit more power in their vehicle? Aftermarket exhaust systems offer a slight boost in horsepower (usually only around five hp) but come with nearly a 20 pound-per-foot increase in torque. These increases are due to better flow through your exhaust system, which allows your engine to breathe easier.
Increased Life Span
Your car’s stock exhaust is meant to do its job and nothing more. Aftermarket exhaust parts are made of better materials (typically stainless steel or aluminized steel) that last longer and require fewer trips to the auto shop.
Better Fuel Economy
Paying for less gas is never a bad thing. While you won’t see massive savings after upgrading your exhaust system, using five percent less gas over the lifetime of a car adds up. The average American spends $3,000 on gas each year, which results in an average savings of $150 per year.
Exhaust systems generally cost around $1,000, so you may make that money back in gas savings after less than 10 years.
Headers vs. Exhaust System
Some people upgrade their exhaust system first and others modify their headers first. It makes sense to do both, but there are different schools of thought on which deserves the initial upgrade. Before you make any purchases, research both to learn their unique benefits.
Now that you know why you should upgrade your exhaust system, do yourself (and your engine) a favor and increase your torque while saving money on gas!
