I have a 2006 S2R 1000 I started looking for a exhaust system everything from headers and complete systems too many to choice from. I am not looking to get the nosiest bike just something pleasent and deep. the Zard looks interesting. the idea of the sparks header and cored stock cans is possible If I could find a distributor for spark. I have read so systems have a clearance problem at the right heal and melt boots!!!!! can remember which. Any way the point was to get a list of exhaust mods and get comments on the plus and minus points on what is out there. GIVE UP A STRAIGHT UP HONEST REVIEW OF WHAT YOU HAVE DONE.
