Welcome to the club! I think it is safe to say that most of the people here have about 200k on their cars, so we know how that goes. As for the exhaust, BMP design sells the Supersprint, which is great and is about $500. The only other that I have heard and liked (and thus bought) is the Magnaflow p/n 11265 muffler. Cost $71 plus $77 for install with a dual tip. Search the forums and you'll find it. The paint on your car looks really good...
