does anyone know where a good place to buy flowmaster exhaust systems, and is there a difference between flowmaster super 40's and flowmaster 40's, and what is the best flowmaster system for a mustang for 99-04 v6, gt, mach1, ect.

The difference is in the sound quality. Flowmasters are all pretty good as far as performance goes. If your going to install it yourself, order it directly from Flowmaster, Inc The Muffler and Exhaust Technology Company manufacturer of performance exhaust systems, mufflers, exhaust kits and if your looking at having it pro installed check out Midas. They will sell you and install the muffler for like 150 a pop so 300 for dual exhaust. More if your looking to convert a v6 to dual exhaust though.

The difference between the 40's and Super 40's is the aggressiveness of the sound. 40's are more mellow than the Supers. If you really want the most aggressive deep sound get a pair of Super 44's.
