Default Tuning?

I am new to HD as of January, but have been riding for about 20 years. I bought an '11 Sportster forty eight and added some S.E.II slip ons. It seems like it still runs fine, but maybe a little sleepier. Can this hurt my motor if I don't spend another $500.00 on a SERT or PC and tuning? If so, how long will it take, because, while it's not in my budget right now, it can be within a month or so. Do I need to Immediately remove the pipes if I ride 20 mi. a day?

If you only added slip on mufflers and left the air box alone, you should be ok. If you started changing other things then you will need to get a re-tune.
