I just bought a '98 GL 2.0 (K&N air filter isall I've done so far). I want to improve the exhaust first, but my limited knowledge and budget plus the different views I read on this forum cause me to be confused. Is the biggest bang for the buck gotten with a slightly modified single? What exactly should be done to a single? Or should I be looking at a single to dual, and, again, what are the recommended mods in this scenario? What is this CarDoc's system, and what is the address of his web site? I'll have a lot more questions in the future, so be patient with me.
