At the time not too many bikes with the FatCat so out of all the bike events and shows that I went to, I never saw one. I'm on my third set of pipes. First set stock pipes, second set D&D FatCat with the standard baffle (Crashed), third set D&D FatCat with the quiet baffle.

The D&D FatCat looks like a cleaner set up because they have two head pipe heat shields, one continuous shield that covers the head pipe from the head to the collector on each head pipe. The only exposed joints on the D&D FatCat are right where the collector and baffle connect.

Also The D&D FatCat's head pipes are much closer to equal length then the Thunderheader. I don't understand why the Thunderheader has a longer rear cylinder head pipe, usually you would want equal length head pipes so the cylinders can be more balanced and breath the same.

When I was looking for an exhaust set up I wanted it all, fit, finish, and performance. I looked at all the 2 into 1's (January 2006) and in my "opinion" the D&D FatCat was one of the better quality set ups out there.

Like "powerlab's" bike below. Looks like a nice set up, but they should have put the oxygen sensors on the back side of the pipe.
