Video Description:In this episode, we interviewed Shawn Gibson from Gibson Performance! Here are some of the highlights from the video:
*At 1:21, he talked about how Gibson's goal with their exhaust systems is to give you power gains and torque gains without giving you an overbearing sound inside your vehicle.
*At 2:50, he talks about their 100,000 square foot facility in California and the types of R&D and engineering they do their for their products. They also manufacture all their parts in that facility.
*At 3:19, they talk about how they do bending, welding, polishing, tipping, coating, and all other phases of the manufacturing all in house so that they have total control over the quality of every product they make.
*At 5:50, they talk about how Gibson products come with a lifetime warranty, and why they're able to offer a warranty like that.
*At 6:37, he talks about how Gibson headers are made using the thickest gauge material, and the different coatings of header options they have available. He also explains how their headers come with the gaskets and bolts, so customers will have everything they need to install it.

After finding various methods to increase performance through improved muffler designs, the Gibson family began and expanded their business into one of the largest and most trusted aftermarket performance exhaust companies around.
Now, with a host of engineers and technicians, Gibson Performance is larger than ever, but it has not lost its commitment to building cost-effective exhaust systems that deliver more performance for the dollar. This includes designing exhaust systems that make more power across a wide RPM band, where enthusiasts need it. High peak horsepower gains are important, but Gibson decided that making horsepower and torque in the lower RPM range would benefit customers who want more towing power, passing acceleration, and improved fuel economy.

Q: What is a muffler? Are there different types of mufflers?
A: According to our resident expert Deryl Atanasu, Mufflers are positioned by the manufacturer where there is space on the car. All mufflers tend to be placed behind the rear axle, as this allows a lower floor-pan in the passenger compartment. Vehicles with single exaust generally have the muffler placed in a direct line with the tailpipe and just before the exaust tip. Some high-performance vehicles have a dual exaust (i.e. corvettes), where both left and right sides have a muffler in a direct line with the tailpipe and just before the exaust tip. Other vehicles (i.e. camaro, firebird) have a single exaust pipe going back just past the rear axle. It then enters a muffler that is mounted in a side to side position. From there two tailpipes exit the muffler and extend to the rear or out the side of the vehicle behind the rear axle.
