i lol'dnot enough detail in the question to answer. what class? over all? world record? burd? base race? every day driver? official? ido you mean street C like your in??
all you need to know is that anything over mid to low 150's is crazy loud for a daily set up. i do a 151 and almost NEVER turn it up. total watse of money IMO. i would not do it again unless i was going to compete.
there are plenty out there in the 160's on music which is just insane for a daily driver
