http://www.graydonproline.com/ how do they sound? How loud are they? do they perform good? please tell me what you know, Iam thinking about putting one on my Z 400. Thanks

 

The raptor head pipes they run are exactly the same as the ct head pipe. The silencer is different. I would imagine that this similarity might run over into other bikes.

I havent heard one in a while, but from what I remember they were pretty loud. Somewhere in the 102-105db range.

 

THAY ARE THE WORST PIPE EVER MADE!!!!!!!!!!!!!!!! I HAVE A FRIEND THAT HAS HAD ONE ON HIS DS 650 AND IT HAS FALLEN APART 6 TIMES AND THAY WILL NOT FIX IT FOR HIM THAY SAID IF HE SENDS IT IN HE WILL HAVE TO PAY FOR SHIPPING BOTH WAYS AND PAY FOR THEM TO FIX IT I DONT THINK SO WHEN A PIPE FALLS APART AFTER 10 RIDE IN A FIELD THAT TELLS U SOMETHING!!!!!!
