Reply to "Mind Train Exhaust Availability"

There have been anecdotes that say “backpressure” helps generate more torque…. but I don’t believe it .…. my comments are also anecdotal.

If you have the Mind Train headers, those are the headers I would use with the Mind Train tail pipes. I would eliminate restrictions and pinch points. Back pressure is bad. Very very bad. The back pressure inherent in any exhaust system, especially one with mufflers, is more than enough. There's no reason for anyone to go out of their way to create more.

Did you know the original headers sold by Mind Train to accompany their tail pipes were designed by Cragar the chrome wheel company? Cragar sold them independently before Mind Train started using them. They were (and still are) good headers.

Muffler design is a compromise between size, sound level, longevity, and back pressure. Magnaflow mufflers have an excellent reputation for high output and reasonable sound level, even in smaller sizes; but they have poor longevity. They use a fibrous packing material to achieve their sound level performance and that packing material loses its efficiency as it fills with carbon and unburned oil and gasoline particles (dirt bikers call this stuff “splooge”). This is true for any muffler that uses a fibrous packing material to deaden sound, like the Mind Train exhaust system. Other mufflers which use baffles to reduce sound level are often louder and/or impact an engine’s output to a greater degree. Mufflers which are both quiet and have good longevity will impact an engine’s output the most, unless they are very large. That describes the GTS exhaust. We don't have the option of "large mufflers" with Panteras.
