Flow Tests
Source: by BroaderPerformance.com via miesk5
This is a chart of popular performance and a few stock type mufflers I have tested on our flow bench. These were all the most popular mufflers sold and installed at a local exhaust shop. Straight pipes have been tested and are used to compare these mufflers to "potential" flow of a muffler. When running a performance muffler on the street there are many more things to consider then just good flow. For instance pleasant tone and enough sound reduction to avoid any "unwanted" attention from local authorities. One thing to keep in mind is how restrictive tailpipes are. You can have a great flowing muffler but if your tailpipes are restrictive you may not be getting any gain from loud, high flow, and not to mention sometimes "expensive" mufflers. If you would like your mufflers flow tested and evaluated we offer this service at this time free of charge provided you pay the shipping costs. These mufflers are tested for the benefit of all and tests are not conducted for profit or to tarnish the reputation of the many quality products on the market. This chart is intended to help you get what's right for "you".
and another flow test chart
copied some good muffler information from the November issue of 5.0 Mustans & Super Fords. For performance and sound comparison of several mufflers, look below.
These will allow you to compare low end torque, and high RPM HP, and sound levels at differant RPM levels.
The test vehicle was a 1990 Mustang with a 5.0, built as a 306 with Twisted Wedge heads, Thick Flow Track heat manifold, 75mm throttle body, AFM N-91 cam.
The Borla XS was the best performer, but at over $150 each, out of the reach of most. Next on the top of both low end Torque AND High end HP, is the Magnaflows, and with a choice of coated steel, or stainless."
