WILL MY RESULTS BE THE SAME AS GIBSON TEST RESULTS?
Gibson literature provides test data for each product that comes directly from evaluating different vehicles on a Clayton chassis dyno meter.
WHY IS GIBSON THE BEST EXHAUST SYSTEM?
Nothing performs better, looks better, or sounds better than Gibson performance exhaust. Gibson’s research and development team invests many hours to ensure its products stay competitive and perform the way they should. Quality, value, and technology! Gibson is committed to the development of state-of-the-art exhaust products that improve the performance and the sound of your vehicle.
WHERE DOES THE POWER COME FROM?
Turbulence exist at every point the exhaust gas “pulse” enters or exits an exhaust component. Gibson reduces turbulence to the absolute minimum in two ways. First their muffler reduces turbulence with it’s Superflow™ design which assist the exhaust gas in its flow out he system. Second, and most important in the reduction of turbulence, is their “slip fit” joining of all components. (Each pipe fits into the larger opening of the next downstream exhaust pipe.) This method contributes little turbulence when compared to “ball-and-socket” or “flange-and-gasket” joining which can create substantial power robbing back pressure and turbulence at each component joint. Or worse, a misaligned gasket or socket can actually create more back pressure than your current stock system!
There is a 34% (or more) exhaust restriction in the typical factory muffler. Gibson Superflow™ mufflers only have about a 5% restriction because the company "custom powertune" every muffler specifically to each vehicle. Other brands of aftermarket mufflers have about 20% restriction. That is why Gibson consistently outperforms the competition on laboratory "flow bench tests" and, more importantly, when you want hill climbing, stump pulling power and torque! Another contributing factor is the mandrel bent pipes Gibson uses. Through "mandrel bending" the opening diameter of the pipe is kept constant, even through the bends. This consistent opening size allows the exhaust pulse to flow smoothly without power robbing restrictions or backup.
WHAT IT WILL SOUND LIKE?
Gibson products are designed and tested on factory vehicles to meet legal sound limits, with the exception of Gibson’s Super Truck Exhaust. If other products are installed, the overall combined effect may exceed the allowable limits. Every Gibson system is engineered to provide a civilized tone. In most cases, this will be moderately louder than factory, but with a rich throaty tone that is pleasing to the ear. Each Gibson system is quieter in the cab than any other competitive. You will get the big-block sound at the tailpipe, where it belongs. No annoying sounds, vibrations, hiss, or rumble in the vehicle so common to other systems.
WHAT TOOLS DO I NEED?
Socket set, wrench set, and a hacksaw.
WHAT KIND OF PERFORMANCE GAINS CAN I EXPECT?
Gibson cat-back systems deliver performance and increase torque that you will feel, with improved acceleration, hill climbing, and passing power. Typical performance gains on fuel injected V-8 will be anywhere from 10-25 horsepower and similar numbers for torque. For V-6 applications, you will see a gain of 10-15 horsepower. How much performance you gain will depend on the condition of your vehicle and the upgrades you have already made.
IS THERE ANY WELDING REQUIRED?
No. Everything is designed as a bolt-on kit.
HOW LONG IT WILL TAKE TO INSTALL THE SYSTEM?
Most exhaust installations can be completed in about 1/2 day. Headers can take a little longer.
HOW IS GIBSON DIFFERENT?
Gibson delivers its power in the 2,000 to 4,000 rpm range. Other competitive systems claim more power by using the higher 5,000 to 6,000 rpm range... This rpm range is never used by street vehicles. Sound is "quieter in the cab" than any other competitive system. You get the big-block sound at the tailpipe, where it belongs. No annoying hiss or rumble in the vehicle so common to other systems. The thicker materials used in both the muffler case and the exhaust piping, as well as Gibson’s patent pending "flow tuning" chambers in every Gibson Superflow muffler, keep the sound "in the system" until it exists at the tips.
HOW DO I KNOW IF I'M BUYING REAL GIBSON PRODUCT?
Every Gibson muffler has the Gibson name embossed in the case. If it doesnt say Gibson on the muffler - beware, its not a genuine Gibson muffler.
HOW DO I GET THE MOST POWER?
Maximum engine power can be released by adding Gibson headers to any of Gibson cat-back systems.
Gibson delivers its’ power in the 2,000 to 4,000 rpm range. Other competitive systems claim more power by using the higher 5,000 to 6,000 rpm range... this rpm range is never used by street vehicles and seldom by high performance vehicles.
DOES GIBSON SPONSOR VEHICLES?
Yes, Gibson does sponsor vehicles.
DO I NEED TO MAKE ANY MODIFICATIONS OR BUY ADDITIONAL PARTS TO INSTALL THE SYSTEM?
No. Gibson systems are designed to be completely bolt-on to your vehicle. Factory locations are utilized and all necessary installation hardware is included in the kit.
CAN I INSTALL GIBSON SYSTEM MYSELF?
Yes, many of Gibson customers enjoy installing their Gibson system. In fact, its a tougher job to remove the factory system than to install a Gibson exhaust.
WILL IT VOID MY FACTORY WARRANTY?
No, all of Gibson street exhaust products are 50-state street legal. Gibson headers are 50-state legal and c.a.r.b. approved. In fact, it is illegal for a dealer to deny you the O.E. warranty because you have changed the exhaust system. More Information.
CAN AN AUTOMOTIVE DEALERSHIP VOID GIBSON WARRANTY?
Your rights are protected through the Magnuson-Moss Warranty Act, 15 USC, 2302, and the Clean Air Act, 42 USA § 7541.
You have the right to buy high-quality, reliable aftermarket performance and replacement parts - an affordable and convenient alternative to the vehicle makers parts.
You have the right to use high-quality aftermarket parts and know that your new car warranty claims will be honored. In fact, your vehicle dealer may not reject a warranty claim simply because an aftermarket product is present. A warranty denial in such circumstances may be proper only if the aftermarket part caused the failure being claimed.
You have the right to patronize independent retail stores for vehicle parts and installation. The U.S. aftermarket offers the worlds finest selection of aftermarket products that satisfy the most discriminating customers seeking personalized vehicles for todays lifestyle.
HOW MUCH LOUDER ARE THE SYSTEMS?
The split rear system and the dual sport system will be about 5-8 decibels louder than your stock system. Their quietest system is the single swept side. It produces a nice deep throaty sound outside, and is just slightly above stock in the cab.
FLOW. BIGGER VS BETTER?
Too large of a pipe without the proper muffler will reduce low end torque but increase top end power. Gibson does not build their exhaust systems to flow as much as possible, but as efficiently as possible. That’s why the right choice is a Gibson exhaust!
