I like the idea of having cut outs on my exhaust. Especially when you can adjust the opening on them and control the sound. I was wondering about changing the positions on them from open through closed...does this effect the computer?
When I put my Halltech Stinger on, it took about 100 miles for the computer to stop giving me bogus read outs.
Do the cut outs cause any other problems? I tried a search in General and Tech but found nothing on this. Other than the Stinger, I'm a stock 2003 A4 coupe. Thanks.

I've never had cut outs but I hear they leak. Are you looking at the QTP's?
Mine don't leak at all, but they are manual, not electric. Mine is based on the old 50's-60's cut-outs for you old timers of which I am. I used a short piece of 2" carbon steel pipe threaded on one end and cut the other end of the pipe at 45 degrees and welded it to the exhaust just as it straightens out after going over the rear axle. If you want to quiten it you just screw on the 2" pipe caps that has a large nut welded to it to allow you to use a wrench on them for tightening and uncapping. I keep a folded piece of plastic (lg. garbage bag) in the car to lay on if I need to install/remove. The sound so good open that they are rarely closed. Total investment including welding labor was less that $100.00.
