The exhaust system that comes on your factory truck is generally a compromise between quietness, ground clearance and performance. Often times a factory exhaust will not handle the rough offroad beating we all know you're going to give it once you decide to leave the bitumen.
Adding a performance exhaust system to your vehicle not only enhances the vehicle's performance, it also makes it look and sound better. An added benefit of a performance exhaust is that it is often made of stainless steel, therefore it won't rust up after your first trip on the beach.
