I have a 2010 Camaro L99 ss/rs. I have kooks long tube headers,fast lsxr intake manifold,vararam intake,bbk 102mm throttle body,corsa sport catback exhaust, and a tune.soon getting a comp cam. I was told that my corsa mufflers are restricting some of the power and I have been looking at some borlas. But I don't know which ones will fit and will give the most gains. Help?
