None of them sound high pitched so far. IPE/Innotech is working on something. But, be patient and be willing to do some research on your own - coming to the forum without doing any previous research just makes you come across as "FEED ME" 
This early (the cars have been out for less than 6 months) you're gonna have to be willing to throw in if you want good info. |
-ARK Performance is also coming out with one
-iPE (cant wait for this one)
As far as the best sounding and highest pitch, your not going to get an answer until a majority of these exhaust systems are out and people have them. My answer for the loudest would be the iPE system, all their products are super loud haha.
