Sounds like an uncorked Mazda rotary at the drag strip, annoying. Honestly I've never liked the sound of Indy cars, Lamborghini's, Ferrari's..... I like cubic inch V8's
I remember watching my first Long Beach Grand Prix back in 1998 and the cars sounded so bad ass like this. It never was the same about 4 years after. That sound had me hooked to all this shit I have done since then.
If I hit the lotto, this would be my first purchase. That sound is fucking amazing........
