4×4 & SUV Aftermarket Products
Our aftermarket performance exhausts are designed to improve the look and sound of your car, and it’s performance. In general, the goal of aftermarket performance exhaust systems is to increase the engine horsepower by reducing the back pressure of the factory exhaust system.
Frequently a side effect of a free-flowing high-performance exhaust system is a healthier engine sound, which is desirable to most people.
Aftermarket performance exhaust systems are a stylish upgrade to a regular SUV.
De Graaf Aircraft Mufflers
De Graaf Exhaust Systems manufacture new, rebuilt, and overhauled aircraft exhaust parts for general aviation aircraft. This includes aircraft exhaust mufflers, aircraft exhaust stacks, and many other aircraft exhaust parts.
We also stock the attaching parts such as clamps, gaskets, and stainless steel hardware for aircraft exhaust systems.
Our Stainless Steel Exhausts use aircraft quality 304 Stainless Steel tubing. Stainless is so durable, most exhausts made from it will be a better choice because it maintains an extra measure of durability at weld points and through the bends.
