Exhaust systems get ripped off. They are usually the last systems to get addressed by performance drivers, who put a majority of work into turbo systems or custom tunes. And a lot of people think that gearheads mess with it just to make our cars sound louder.

At Modern Automotive Performance, we never get exhausted talking about exhaust. The reason for investing in an aftermarket system is about so much more than the sweet sound of an engine roaring. It’s simple chemistry: If we add air to our engines for more performance, then we need to make room for new air as quickly as possible. Stock options on Lancer Evo or Subaru WRX models aren’t made to drain the engine at higher performance levels. A custom upgrade is built specifically to enhance that airflow, giving you more horsepower and efficiency every time you step on the gas or use a boost.

That’s why we carry a wide lineup of sport exhaust systems, from individual pieces to full kits, made by some of the best manufacturers in the industry. We take exhaust so seriously that we also make our own branded exhaust systems in our own facility. We use 304 stainless steel for extra durability and life, and ensure every component is forged to fit your vehicle.

We’ve been helping customers with performance upgrades since 2006, and have a staff full of people who can help answer your questions. Our customer service — from our low prices to our fast shipping — has earned us a reputation with a legion of fans. The time and money you spend are a big investment, and we want to help you make the best decision for your driving dreams.

Whether it’s wowing people at a show or getting every advantage over the competition on the track, our exhaust systems will help your car perform its best.
