The only real "emissions control crap" on the SV are twofold; the air injection of the exhaust to burn hydrocarbons in the tailpipe before they go out, and extremely lean mixture in the lower rpm range.
Enriching up the mixture is going to see some power LOSS.... offset by the increased flow of a full system and better filter.
You might see 1-2 hp with just a can; a good full system will same you 10-15 lbs and provide for better flow.
Most of the gains have to do with the initial state of tune and the care to which the bike is re-set up and mapped.
