Borla or Magnaflow... You can't go wrong with either. Check out CFM (Central Florida Motorsports) they are a sponser on the forum. They will price match Magnaflow CB exhaust systems if you can find one cheaper price anywhere on the web. The Borla CB system is $599 at CFM.
I'm getting ready to have my headers wraped, instal a CFM "street" HFC, CFM Flex Pipe and a Magnaflow CB system (all brand new parts); and have it all done all at once with obviously all new gaskets and exhaust hangers.
