rasp isnt that weed whacker buzz noise. thats just ..... shitty sounding exhaust. you only hear rasp when you let off the gas JUST as the rpms are about to the 1k-500 level.
heres a raspy **** example.

listen for when the engine RPM's drop from rev, to almost idle. its that noise thats like someone sticking there toung out and blowing.
and good for you, you get a bro high five. im not lecturing you about THIS car. Im lecturing you about ALL cars. physics just so happen to apply to all of them. just sayin. so stop acting like a know it all and do the research for yourself. Im sure for your super ultra 1337 "in your mind" build only useful on a track that about 2% of the community would ever care to do will be awesome. but im talking about the real world, where dyno numbers arent the only thing that matters about owning a vehicle that most of us drive daily. derp
