Flowmaster C218250350 Exhaust Header Collectors to Length

1-Pair, 2.125" Primary Dia. / 3.50" Final Dia., 24.5" Length. The large "D-shaped" ports in these collectors create a low pressure that pulls the exhaust from the cylinders for a cleaner burn and broader torque curve.

Note: For use on race vehicles - not intended for street use.

Features:

• Race Proven Technology
• Patented Design that Creates Low Pressure Zones for Better Scavenging
• Gives a Broader Torque Curve
• Made in 16-Gauge Aluminized Steell
• Fully MIG-Welded for Durability
• Header Tabs for Quick Installation and Removal Included

All Flowmaster Exhaust Components are tuned for maximum performance. The Collectors are no exception. Every little detail counts in racing, and the exhaust is one of the most decisive factors. By shaping the components of the exhaust system in a way that makes the system use the forces of the exhaust gases to create an "air pump" that sucks the gases out of the cylinders, it is possible to get more torque and horsepower from the engine. An improperly designed exhaust can rob the engine of a lot of power by reflecting the exhaust pulses back so that the outgoing pulse meets a reflected pulse and thus is stopped on its way out the exhaust pipe. The Collector is a critical point in the exhaust system. This is where a whole herd of horses can be lost or gained. Don’t let your horses run away, get Flowmaster Collectors and see the number of horses coming out of your engine grow.

The original Flowmaster technology was born on the racetrack over 25 years ago. There was urgent need for a sound solution for Sprint car racing at local California fairground events. Their sound level of the Sprint cars was deemed too high and the continuation of the racing was threatened by protests over the excessive noise. Flowmaster founder Ray Flugger invented and patented a new and innovative technology that not only resolved the excessive sound issues of these high-powered racecars, but also increased maximum horsepower and provided an increased and broader torque curve - an unheard of byproduct from competitive mufflers in use at the time.

The highly devoted R&D department of Flowmaster Inc. actively searches for new challenges to resolve, and is constantly working with leading race teams, engine builders and race organizations in the quest to improve and develop new technologies. Flowmaster's developers are focused on developing greener, more positive solutions to keep racing safe for all participants, fans and neighbors, while achieving the ultimate goal...Winning! No other muffler company has dominated racetracks around the world like Flowmaster has in the past and present. Nor will they in the future. That's the Flowmaster pledge to customers. The company is confident to make that statement, trusting that its developers will constantly produce ground-breaking improvements in muffler technology.

Flowmaster® has its roots in solving the engine noise problems encountered by California racers in the 1980s. In 1983 Flowmaster’s founder, Ray Flugger, created his first patented design of racing silencers, which dampened noise with minimal loss of power. Ray attached handles to ease carrying the square shaped race mufflers through the race pits, and the mufflers became known as the "suitcase mufflers." Today, the innovative Flowmaster mufflers are the result of years of development with top race engine builders, thousands of hours of dyno research and "real-world" on-track testing.
