SuperSprint quad pipes for 525 M Sports

[ST02]

Dear MembersI'm new to this forum. I have an 08 CKD 525 M Sports. Thinking of replacing stock xzos w SS quad pipes (cat back, not entire xzos system). My questions are:-a) has anyone installed the SS quad pipes?b) if yes, how is the sound? Too loud?c) is it just bolt on or need to do xtra piping work?d) any problems after installation?Thanks in advance for your input/feedback.Regards,
