I installed this alongside the AMS Widemouth downpipe and my 3-inch catback exhaust system. Install was super easy once the other parts were in place, just 5 bolts. The AMS high flow cat is nice because it has the bracket welded on to bolt directly to the factory fitting. It also has the extra bunge to use with a wideband O2 sensor if needed, but comes with the plug if not. This cat also weighs much less than the stock system. The only issue I ran into was with fitment as the stock system and other aftermarket systems have a bend to make them line up more directly. This wasn't a problem since the downpipe has a flex hose that allowed it to be maneuvered into position and lined up straight, but may be an issue if using the stock downpipe.

      A:  We do not offer buscher products and I am not familiar with their setup.. But, as long as it's a 3" setup there should be no fitment issues.
