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. 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. Today, Flowmaster is comprised of three modern facilities in California and Idaho, employing over workers. Producing over tire-roasting horses, this El Camino is the perfect test bed for this collection of mufflers. 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. While producing a much quieter tone than the other models we tested, the 70 Series still provides much-improved sound over the stock exhaust.

Would love to upgrade my base model exhaust, anyone do it and keep it single exhaust? Not sure I want dials or not I think Mattgendron messed around with his a bit. I removed the main muffler and replaced it with just piping. So I have both tubes from the cats still go into a resonator and then into another resonator that the exhaust tips are attached to. Adds a growl but is in no way over the top.
By hollowman , February 2, in Street. I have true dual exhaust on my silverado. Dual would be louder. Get rid of the flowcrappers and put in some bullets or magnaflow magnapacks. I'm not a fan of a y pipe, x pipe yes.
