2012 CBR 1000rr with Hotbodies Mgp exhaust

I bought this exhaust and I am well pleased. I welded a nut to the midpipe they provided to read the O2. It still needs a power commander but runs with no engine light. It has a ruff idle right now but a PC3 will fix it for sure. The exhaust is loud yet clean. I have a lot of things still to do to the bike but time and money will only tell.
