Sorry bringing this one back to life. Installed mine in June. Yes the S-4s sound great I do greatly suggest though that if you dont like the backfiring you might want to do the AIS block off ( the backfires are loud as hell ) shot a flame out of it. I unfortunately have not done the AIS yet. Yes as we can see the pipes will blue if you are too lean. As for all clearance questions: The right hand turn im sorry but no info there I was off the bike for nearly a year so I didnt push it that far. I think with the heigth of the outer pipe it might just clear. Outer pipe does unfortunately extend a bit over the peg mount, leaves you a bit limited on room for your right foot. If you are short legged like me standing at a stop does take some effort to avoid the pipes as they are quite hot, you can see what they did to the pants on the first ride.These pipes are wide the hell open you can see the down pipe openings from the end of the chamber, LOUD!!! Oh but do they grab some attention. The only problem that I have had with the pipes besides heet and right foot room was that there is a torque-x screw that they are required EPA to use to hold the tip and baffle assembly in the chamber. When Installed the pipes I left the wrapping on so i didnt damage them during the install and missed the screw. I suggest that before the istallation you go by a parts store and get the adapter for the screw and pull it and apply some lock tight to prevent it from coming out. There is enough vibration for it to come loose. Mine came off and I lost the tip and baffle at 60mph with my wife on the back. With that said my dealings with the manufacturer has been EXCELLENT! Doug was an extreme help. Even though the tip and baffle incodent was not considered to be under warranty the owner aggreed to strip and repair if not replace the tip, replace the screw, and replace the glass packing. Very Good Customer Support! As for the vibrations you never really notice the vibes that it does have, cant hear it either. LOUD! There is a visible vibe in the pipes at what rpm range not to sure i didnt catch it, but when you bust these things wide open the vibe stops and they are just WICKED SICK! If anyone has any questions about these just shoot me a PM. Im sorry but I do not have a map for them yet
