The time and money you spend are a big investment, and we want to help you make the best decision for your driving dreams. Typically, a cat-back exhaust system will increase your car’s horsepower by somewhere between 5 and 50 brake horsepower. This will vary greatly depending on the condition of your exhaust and engine, so you should ask your mechanic if getting a cat-back exhaust is the best way to improve the performance of your car.

By freeing up the restrictions in the exhaust system, a cat back exhaust can help your engine to breathe more freely. This, in turn, can lead to a significant increase in horsepower. If you love cars just as much as we do, then you know that one of the best upgrades you can make to your vehicle is a cat back exhaust. But if you’re not familiar with this term, don’t worry – Vandemon Performance is here to break it down.

Our straight-through brushed-finished mufflers are configurable to your desire, smoothing the exhaust note to a deep growl, without adding restrictions, rasp or drone. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise. A cast 3” to dual 2.5” rear splitter creates an ultra-smooth transition, steadily feeding exhaust gasses out of the system, while looking tidy from under the rear bumper. Finally, removable 4” polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle. In addition to high-quality materials and components, the design of each high-performance exhaust system allows for easy, bolt-on installation right out of the box. CORSA exhausts require no welding and can mount directly to your factory connections.

When GM began to work on a new big block Corvette and Ferrari increased the power of the V12 powered GTO’s, Shelby and Ford Motor Company decided to shoehorn the mighty 427 FE motor into the Cobra. By combining Ford’s incredible 6.7-liter Power Stroke® turbo diesel churning out 1,050 lb.-ft. Of torque with a Shelby tuned advanced off-road suspension system, the three-quarter ton truck delivers both serious off-road capabilities with best-in-class towing.
