I know this may sound like a dumb question but I am going to ask anyways. A few months ago, I had a Flowmaster Super 44 OR installed on the KK. I absolutely love it. No complaints there. I only have one problem. I am stationed in Germany as as such must hold my vehicle to the German car regulations which are stricter than those in the U.S. The rule that deals with exhaust noise states that your exhaust may be no louder than 90 dB. I am pretty sure my KK 3.7 V6 makes more noise with the Super 44 than 90 dB. So here's the question: Has anybody or could anybody find out how loud exactly is my KK with a Super 44 on? The Germans rev your engine to half way to redline which is 3000 RPM. If it is louder than 90 dB does anybody know of any way I can quiet it down without having to weld or cut anything? (stock muffler is garbage) Any help would be more than appreciated.

You could try changing the tip out and/or getting a pre-muffler resonator. I don't know how much it'll help but depending on what db you're currently at, it might be just enough to get by the reg.

It's going to be close, but I don't think you will have a problem. If you do, a larger resonator is really your only route short of doing more then needed cutting and welding..
