can someone expand on this?
better yet...
does anyone have a magnaflow system that is going to be at the Garden Grove meet next week?
As I know there will be several that have the zoomers system...
Thanks in advance!!!

Drone is a subjective qualitative characteristic of all exhaust systems. Freuqency and amplitude will vary as design changes. Each persons own "interpretation" of acceptable levels and their own personal auditory capacity wil determine what is appealing to them.
Often times people ASSUME things from previous experience and have not really heard for themselves the actually product in question. Some people assumet that based upon other experiences with products they can make generalizations for all products. Unfortunately that is not goign to lead to valid assumptions.
Example:
F-Body (Camaro / Firebird) Our kit is loud and has some degree of noise both insdie and outside the cabin. This product was designed around a perfromance enthusiast customer ... by definition and market study these people were seeking power as premier and were willing to sacrifice other componets such as drivabilty and comfort. Our cat-back caters to that criteria.
The LX chassis on the other hand is entirely different and our strategy is altered to provide a larger degree of comfort whiel still providing a power enhancing part. These are trade offs but not those made by simple coinsidence.
Our cat-backs are NOT culminations of universal parts and pipes. Pipe diameter, resonator or muffler style, shape, volume and perforation core VARY by application. YES thats right ... putting our universal parts off the shelf together to the same configuration as our cat-back will NOT net the same results. This is why we sell BOTH universal and Cat-back configurations.
Our cat-backs are engineered ... not fitted and replicated. We have a 30,000 sq ft facilty housing two test engineers running two in-ground Mustang and Dynojet dynos, Superflow and Horuba flow benches, 1/3 octave 32 band spectrum analyzers and 4 other engineers designing internals and supporting our Computer Aided Drafting design department. My fabrication and design staff pride themselves in putting out product DESIGNED for its applciation.
It would be interesting to hear some impressions regarding noise / drone / resonance from actual owners ... I know they are out there .... we are still selling over 50 systems a month.
