Love the prochamber on my 97 GT, did not realize MAC was still in business.
They're still around but like jsquared said, quality issues.
I bought a prochamber back before I did the headers, and on the main part of the prochamber (where the downtubes from the engine attach) I had to bend the pipes in with a ratchet strap because they were angled out so weird.
I don't know if they do really sloppy work, don't use jigs when they weld or a combination of the two, but even looking at jsquared's picture I can see how poorly the pipes are aligned on that one.
