Check this link, this is what I did to my long TOR's...only cost me $5 at Home Depot...big improvement,a nd easy to do.
With your short TOR's you may only have two baffles. Just do one set of baffle plates, on each pipe, at a time. Then try it out, and if you want them louder do another set of baffles.
