I have the D&D pipes on mine and I love them. But I never had the TORS, so a sound comparison I can't make. These D&D's sound alot better than the originals I think. They are deeper sounding and rumble more than stock. These are a good deal for anyone wanting to remove the cat box without buying the by-pass box from Triumph. There are better exhausts out there, like the predators, but those will cost you more. If your on a budget, the D&D's are the deal.
Good Luck!
