hi, i read this with interest.
i am looking for one that is NOT loud so if you say it is quieter as the OEM so this would be a good exhaust for me,
normally i would go for a ZARD E-aproved but i think this one is cheaper
do you have torque and power dyno charts (with or without a flash)
did you get this from Japan or bought it in the UK?
thanks for your reply.
