Stock sportster exhaust
I'm looking for input/advice about my exhaust. This is only my second year riding, and I am fairly limited in mechanical knowledge. I have an 08 1200L, with stock exhaust and stock air filter. Plain and simple, I want it louder, but on the cheap, if possible. It had been suggested to me to punch out the baffles. The one who suggested it to me also warned me that it could cause the performance to suffer if I don't change the filter/breather. On the other hand, I have also been told by another rider that he punched out his baffles, without changing the filter system, and it didn't affect the performance at all. Obviously, I'm a little torn, due to my relative inexperience. Can I punch out my baffles and not affect the performance? Any input/advice/experience would be appreciated.

You can punch out the baffles and be fine as long as you don't change anything else. It will not likely get you the sound you want and you will lose a little performance.
Your best bet is to go with some sort of slip-on muffler that you like. That will allow you to get the sound, performance, and keep your stock cans in case of future resale or something else.

I dont think the OP will lose any performance if they just punch the baffle....the reduction in back pressure is going to be minimal...
its just changing the sound that is produced just as a different baffle would in a set of slip ons...just the way my brain see's it...

I'd consider something like Cycle Shack or Rush slip-ons. They'll give you better sound, without costing a bunch. But more importantly, you won't have to permanently alter and/or ruin your stock pipes (you may even want to put them back on when you sell it). If you don't like the way the chopped up ones turn out, guess what, you'll be buying new aftermarket slip-ons or OEM replacements anyhow.

This trick doesn't cost much to do and definitely helps the bike run smoother. It's probably slightly louder than just punching out the baffle plug that is located about half way up the muffler.
This involves using a hole saw to cut and remove the baffle from the muff. Then I opened all of the holes that are drilled in the baffle to twice their original size. Then I added three more rows of hole to the aft end of the baffle and lastly I completely removed the baffle plug, hole saw again.
You will have to take them to a welder, unless you can do it yourself, to reinstall them. But it makes a noticeable difference in sound and power.
I think it cost me 20 bucks to get them welded back in.
I bought an extra set on ebay and kept my originals, but looking back I wouldn't buy the extras, I doubt you'd put em back on.

Many thanks for the replies. I appreciate the input. I was actually able to buy a used set of stock exhaust, on the cheap, with the baffles already punched. I'm going to be installing the mufflers and see how that pans out. Thanks again for the input. We'll see how it goes.
