MIL.SPEC HIGH Pressure Throttle Shaft Seals/100 Cell Cats are available
THese are weld-in units, so you'll need a donor testpipe. Any testpipe should work, you'll just cut it to fit the cat and weld-in. The only people who can't do this areAMS customers, as AMS uses 3-blot flanges. For those exhausts, you'll need an AMS test pipe.
For the moment we are producing weld-in units. We have made our cats available to vendors. If such a time exists where we find a reliable fabricator who does top notch work at a price that makes sense, we may start producing bolt-on units again.
