New here guys so sorry if a dumb question. My 03 r6 i bought with a set of aftermarket headers and a gytr slip on. Last summer my friend tiped my bike over and scratched the exhaust all up. he felt bad and got me a high mount micron slip on. Now as for all i know the bike was mapped with the pc3 for the headers slip on and high flow air filter. Now The gytr pipe felt like it was a little rich and lots of black on the end of the pipe. Plus i got a burning sensation in my eyes and could smell the gas. Now i just put on the micron and i went for a ride. It is way more responsive and feels alot smoother. It does not back fire as much when i let go of the throttle and sounds better. Does not smell like unburnt gas to much. I would say it feels just right with the map that is on the pc3. My only fear is that it is lean. I have only about 15 miles on it so there is no black on the exhaust yet and thinking about pulling plugs just to early now to see. I did feel one weird thing i never felt before and that was a slight i mean slight vibration in the mid rpms with this exhaust. I do not know if that means anything. So just wondering if i should change maps to a micron specific or leave it.
