I run headers hi flow cats in to oem cat back and it's perfect no droan and barks nicley, still quiet at idle except i run a rough idle bump stick and gives a bit more aggressive idle tone with some rock n roll
Impo cat back afternarkets ill provide add db's to idle and over all tone/ sound but minimum performance gains and potential droan at cruiz rpm 1500 - 2000 rpm
