Removal of Emissions

[Guest]

Rids the bike of 2 - 3 lbs, gets rid of a small backfire / popping noise when exhaust is changed, and in my case, gave me one less thing to scrape my knuckles on while changing oil filter. Have not found the disadvantages yet.

Any advantages or disadvantages on removing the emissions ,I believe it's called the pair valve, in front of the engine cases on the busa.
