In our tests, the 70 Series produced an average of 82 decibels at 3000 RPM from a distance of 30 feet. The interior sound levels, as advertised, are very pleasant for those that prefer interior comfort while still catching the attention of those outside the car. While producing a much quieter tone than the other models we tested, the 70 Series still provides much-improved sound over the stock exhaust. вЂњThis is one of our mildest mufflers that fits on a wide variety of applications, and if you can fit it on your vehicle, itвЂ™s one of the big choices these days,вЂќ said Benty. This muffler employs FlowmasterвЂ™s patented Delta Flow Technology which reduces interior resonance and increased efficiency, and is aimed for use on trucks, SUVвЂ™s, RVвЂ™s, tow vehicles, and high performance street cars such as our El Camino in which a quieter tone is desired. The 70 Series Big Block II Muffler is a three-chamber design, which incorporates a longer case for increased volume inside the muffler and lower sound levels. Producing over 600 tire-roasting horses, this El Camino is the perfect test bed for this collection of mufflers. We recently tested five of FlowmasterвЂ™s latest and most popular performance mufflers for a sound comparison on a classic 1972 Chevrolet El Camino with a Pat Musi Performance 509 cubic inch engine under the hood. The companyвЂ™s modern line of mufflers are the result of years of development with racing engine builders, thousands of hours of research and development on the dyno, and real-world testing on the race track and the streets of America. The company boasts the only exhaust research and development facility of itвЂ™s kind in the world вЂ“ utilizing SuperFlow engine and chassis dynos to fine-tune the design and sound of its exhaust systems. Today, Flowmaster is comprised of three modern facilities in California and Idaho, employing over 250 workers. вЂњBetween all of those benefits, there are few products that you can put on your car that do all of those things in one easy bolt-on install,вЂќ says Flowmaster VP of Marketing Cam Benty.

What began as a mission to quiet race cars without a loss of horsepower evolved into designs and products able to not only quiet the vehicles, but increase horsepower and fuel economy and provide a great new sound as well. With humble beginnings in 1983, founder Ray Flugger created FlowmasterвЂ™s first patented design of a silencer for race cars in an 800 square foot barn in Kenwood, California. And Flowmaster Mufflers, a name is which is synonymous with high performance exhaust and whose products emit a truly unmistakable tone, is quite commonly the go-to source to satisfy your high-horsepower needs. If youвЂ™re like most automotive enthusiasts, the modification of your high performance street or strip vehicle begins with the removal of the stock exhaust to make way for a deeper-sounding, more powerful aftermarket exhaust system.
