Wow, high pitch sound on a normal engine? Cool..... Like those I hear from Kancils whereby they want to sound fast and move like a snail.. I love embarrassing those kind of drivers...
What's the point in sounding like an F1 without the action? Please don't embarrass yourself. If you want to sound like a performance car you would have to have a performance car. Otherwise your car would just have that noise whereby the real performance drivers would just drive by and think "god... look at that shit...". People like me and many others I know always talk about this.... and whenever an opportunity arrives, we would show what a real sound which comes with the REAL engine are like.
If you must know. Porsches sound the way they are because of their ENGINE. F1 sounds high pitch because of their ENGINE which revs till god knows how many thousand RPM nowadays. You get those V8s Corvettes, Vipers, and whatever because of their ENGINE. The mufflers just HELPS with the sound and not MAKE the sound. Want to sound like a Vtec but without having the vtec? Pls... that's disgusting.
