Flowmaster news

It is known that Flowmaster mufflers are one of the best there is today, but how do these exhaust parts become like these? Numerous tests and research had to be done to ensure each part’s efficiency.  Flowmaster said that real-time track and highway testing are done, but aside from that its own SuperFlow dynamometer perfects each muffler and exhaust part for the optimum performance.

Flowmaster also uses Bruel & Kjaer real-time spectrum analyzer that takes care of the muffler and exhaust system research and development. According to Flowmaster, “not only can the analyzer be used to measure sound levels, it can also be used to fine-tune exhaust tone and locate unwanted vehicle interior resonance sources.”
Flowmaster also has a SuperFlow SF-7100 Engine test system which is a water brake engine dynamometer capable of determining endurance and performance. According to Flowmaster, “the brake will absorb up to 2000 lb-ft of torque and the computer-controlled system will record up to 50 separate channels of data each dyno pull.”
Along with this facility, Flowmaster is also equipped with a SuperFlow SF-840 chassis dyno. It is a Inertial type chassis dyno that is controlled by Eddy Current electric brakes through a dual computer. The dyno can keep the vehicle steady and can power up to “1000 hp at the rear wheels, and a 200 mph top speed.”

From these technologically advanced procedures come high quality mufflers that can increase horsepower, torque and fuel economy while minimizing exterior sound levels and reducing interior resonance of the vehicle. One of these is the Delta Force race mufflers. Backed by the Delta Flow technology, this muffler “provides superior scavenging of exhaust gases.” It achieves this by using multiple deflectors, which has an advantage over a single deflector because the multiple deflectors reduce the chance of turbulence.

Performance can be heard and that is what Flowmaster does best.

As Ray Flugger, founder of Flowmaster mufflers, dwell on new designs for the track, his basic design has not yet been finalized. In order to perfect the engineering, Flugger used shoe leathers and worked with racers at drag strips and racetracks all over the country. It wasn’t long that he developed the balancing chamber, the Power Chamber. He was alos make notable contributions to exhaust engineering like header length and configuration for several major race teams.

Flugger continued to developed his ideas and did more dyno testing, worked on velocity improvements inside the muffler and really understand the operation of the muffler as it develop peak torque and velocity.
To prove the performance boost his muffler design is capable of, Flugger tested on circle track cars, drag racers and at Sebring with Jack Roush. He visited these locations and offered his mufflers along with developing the engineering together with various racing teams. His muffler would be fitted with a handle from a suitcase and later became known as Flugger’s Suitcase Mufflers.
Flugger’s Suitcase Mufflers proved to be great engineering as more racers felt the edge it gave them and helped them comply with sound regulations imposed on many small circle tracks across the country.
Until today, many racing victories are attributed to the edge that Flugger’s chambered mufflers gave.
In celebration of the success, Ray Flugger made a limited special stainless Signature Edition,Classic Two-Chamber Muffler. Only 1,000 units were made and each of these was personally etch-autographed, and numbered by Flugger.

Ray Flugger, founder of Flowmaster performance exhaust, had much technological advancement and perfected the chambered muffler design.

According to Flugger, “It all started when I realized that there had been virtually no new technology developed for exhaust since just after World War II. We knew open exhaust changed performance but no one could pinpoint quite what was happening or really whether it was a plus or minus situation. I started to figure out just what went on inside the exhaust system and discovered there was a lot of interaction happening.”
Flugger then concentrated on the existing muffler design and found that almost all the designs inhibited exhaust flow. “I remember testing traditional glass-pack mufflers and found they restricted flow yet produced a pleasing rounded frequencies I wanted. That got me thinking about how I could design a muffler that could improve flow and create a great sound.”

He then researched further until he came across an old motorcycle magazine discussing the “the impact of exhaust flow on headers and confirmed how the exhaust pulse involved sound, heat and airflow.”

This newly confirmed fact only made him realize that in order to improve time horsepower and torque, combining valve overlap, head designs, tubular structure and muffler design are needed.
A lot of trial and error went to his designs until it became the Flowmaster-chambered mufflers known today.
According to Flugger “I could feel it in my bones that I finally had the engineering concept right! I knew that I needed to perfect it, and that’s what we did over the next ten years!”
