I know that I can use a Thrust Glasspack but I was wondering if anyone used a Borla or Magnaflow or any other pre-silencer on their cars that does not stop exhaust flow? I want to replace my rotting one next week. Or should I just do a straight pipe. :) 91 NX2000 with work. 97 Maxima SE, smooth and powerful automatic http://www.angelfire.com/ny/ianjiggyroom/IansNX2000page.html
