I just installed Fentons on my '55 1st 235. I bought Patrick's all stainless steel exhaust system, and mated it up to the Fenton's. The stainless muffler is 2 in, 2 out, and the pipes come out of the driver's side rear shotgun style. The sound is incredible, and I definitely picked up some HP as the improvement in acceleration is noticeable. I hate exhaust work, but Patrick's set up is a snap. No more exhaust fumes in the cab...yippee!
