Who makes the best manifolds for drag racing? I have a set of profab headers and I haven't been that impressed, they leak in a few different places and I would like something that doesn't leak. Also would be interested in a used set if anyone has anything available.

As others have said, contact Rick @ ProFab. I have his cast manifolds/up-pipes and they have held up great on my truck this past season sled pulling as well as daily driving. I know drag racing you can get away with more in terms of parts designed for lower duty cycles (i.e. the header style manifolds) due to the cooldown time between runs and the lower duration sustained heat loads.

Any idea when we will see them available?



Don’t hold your breath. This has been ongoing for 4 years. First sets went to Fleece for testing and from what I understand and what Leen told me back then was if they aren’t better than what’s already on the market he isn’t going to make them for the public.
