Spintechs- Which Ones?
 

I'm pretty sure I'm gonna go with spintechs, I know they have the prostreets, super stocks, and pro-shootouts and I'm assuming they go in that order from quietist to loudest. Anyone have a soundclip of their car with any of these mufflers (already looked at mustangexhaust.com). I'm gonna order them from dr. gas' site along with a 3"- 2 1/2" longtube header X-pipe and go wiht BBK longtubes. How do the prostreets compare to FLowmaster 40 series as far as loudness/sound, do they at all have that raspy sound like glasspacks? I'm looking for something deep/hollow sounding like the 40 series, only a little different. Any info-opinions are appreciated.

Don't have a sound clip of my car and if I did it would only be misleading. (400+ cubes & bigger exhust)
As goes for a what muffler, I would say the sportmans sound somewhat like a 3 chamber Flowmaster. The Prostreet sound like an old classic 2-chamber Flowmaster from back in the day. (early 90's). I would say if you want it loud get the pro-street. Sportmans or quieter, and the Sportmans xl's are the quietest.
These are all in my opinion, so someone else might differ.
Good luck

My old combo was a 306 w/ 3 inch Prostreet mufflers and it sounded wicked!!!! To loud for the street though, (police magnet)
If I had to guess I would say they sounded like a 1 chamber.
