to me and other purist out there sound is a bi-product of performance.
so if you have enhanced the performance of your car the sound comes naturally.
if you have enhanced your sound to represent performance you are a poser and that=Rice:icon_bigg
Example
"hey that exhaust sounds great. what kind is it?"
this is were you either lie and say "it's a SPT or STI" or you tell the truth
"i put some washers in the exhaust flange to create a leak,cool huh."
this is were most purist will stop talking to you and walk away thinking rice-boy...
