These will work.......the ever elusive spitfires. They work well but they aren't TTI's. Downsides are you might have trouble getting them. (I had no trouble but quite a few have, I bought 2 sets) The collectors dump right above the torsion bars and you have to weld the flange on. Past that they are a cheap alternative to the TTI's or Dougs. They do not go through the fender well.
