New to the forum and thought I would drop a line. I just purchased a 2011 Mustang GT premium with 21k on 7/30/13. It has a C&L cold air and mass air meter, Steeda axle back exhaust and a tune. I plan on adding LT headers when I figure out what the best bang for the buck is. I will also be adding and x-pipe to the mix as well. Any other suggestions from the locals would be great. I don't want to put on any power adders though.
