I will be getting my TII back in about a week after a full rebuild with porting, clutch, racing beat exhaust etc. but I cannot decide whether to install an aftermarket blow off valve.

Of the guys who have an aftermarket one, does the noise bug you after a while?

 

i have been around them for a long time and love the sound still fun to scare ppl if you have a loud one and intimidate other drivers.. but thats jsut me..

 

Go Aftermarket my friend, ive never gotten tired of that noise
