Well I got a little anxious and decided to be bold about the exhaust. I ended up driving to virginia where I picked up a clean boxster exhaust and got some new pipes made to mate it to the 2.0 IV. I was contemplating cleaning the baffels for a more throaty sound, but did not want to until fully testing the sound of the stock muffler. MAN what a difference. I have never been in my bus this quiet before. I have a sweet tone at speed and the engine is alot more steady with the smooth flow. I was worried it may be a little restrictive (still testing) but performance actually seems to have improved a little. After rebuild this winter with some more output Ill see if the baffles will go or not. At least I know my exhaust wont ever rust off.
