Installed my down pipe today and deleted the cat from the oxygen sensor back. I plan too match the down pipe to the original flat black of the headers to give it bike a cleaner look. Install took a couple of hours with a support bracket also installed to provide added support to the down pipe total plus labor $100. Now my R3 sounds like a true GP bike which is awesome but the sound from the pipe is louder but not annoying at all. The slip on was louder by itself but still on the quite side. With out the cat my R3 has lost another 5 pounds and its noticable it all the right areas. The bike is in need of a full air fuel mapping but as it stands right now the bike is running a little on the rich side with a slight pop coming from the pipe under hard acceleration and down shifting but its not a bubbling popping or anything to worry about. Over all Im happy with my results will dyno tune soon and I saved over $200 over a full system which in my opinion isnt really worth it. Here is one picture I will post more photos soon.
