I used to work for the company in Germany that makes your cat. The Cat is basically a straight through honeycomb of ceramic. It does result in a minor amount of backpressure, but contributes very little to sound reduction.jdsmith1953 said:i removed my catalytic converter elements, it breathes better but i can't say it is any louder.

After I got the bike home I stuck a piece of 1/2" dowel rod down the opening at the rear of the muffler and it almost swallowed up the 3' piece of dowel. Peering down the center of the muffler with a flashlight, I saw there was no baffle to drill through. That means our OEM muffler is straight through, or at least the one installed on my '98 model.
The cat has some sound deadening qualities but it's straight through too. Looks to me if you want to increase sound, you've got to go aftermarket.
I went with Remus on my '98. It's not too loud, compared to Two Brothers or ZTechnic and it's comparable to a couple of Staintune pipes I've heard.
What is so special about that? K-Bikes are legendary for their high mileage. One guy in Holland has over 500,000 KM on his K100.oneydee said:You're kidding right? 170,000 miles?! I'm not sure I believe it.
