Go for it! You won't know if you like it or not unless you hear it in person. The videos give you an idea, but there's no replacement for live audio. Take a hacksaw to the stockers and drive around like that for a little bit. If you don't like it, take the mufflers to an exhaust shop and have them re-weld them back in place. If you do like it, go ahead and have the straight pipes and tips welded in.
I personally am considering going with a pair of 2.5" glasspacks for mufflers.
