Yeah...even my Staintune is a little louder now than it was 20,000 miles ago.
I read somewhere here that someone did something to the catalytic converter which made the stock pipes a little louder.

'04 GT...Orient Blue...Staintune...Ohlins...Power Commander

i removed my catalytic converter elements, it breathes better but i can't say it is any louder.

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.

Besides, who wants a louder bike for loudness's sake only. I thought we were riding BMWs here, not Harleys!

Don't wait for it to get louder by itself. I have 170,000 miles on my K1200RS and it sounds about the same as when it was new.

When I bought my '98 Taxi, I thought I'd do to it what I did to my 900/6, drill out the baffles in the muffler to increase sound slightly and maybe enhance performance.

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.
