the s197 will never sound like a 5.0 or the 2v modulars. i have a 1992 LX, and it sounds totally different. IMO the s197 sounds better, louder, deeper, more evil sounding. my set up is BBK LT's and o/r x pipe, MBRP muffler deletes, M80's welded in before the rear end. i also believe that with the muffler being after the axle, gives more of a tendency to trumpet.

in this one i compare my s197 to my fox, most people like the sound of the fox better, but i prefer the s197. i added this in bc the s197 will never sound like the older stangs, and i dont think we should even try to duplicate it bc it aint gonna happen.
