Got My 2011 SS with the RotoFab Cai and the GMMP axle back exhaust installed.
I actually love the sound as it is .... not too loud, but roars when you step on it.
I want to get it tuned to make sure the mixtures are right and adjust the transmission. Would you go ahead and get it tuned now or get some high flow cats and then get it tuned?
I'm afraid if I get the high flow cats it will be too loud for me at highway speeds?
I like the performance now as is, I just want the transmission adjusted for harder shifts and spin the tires a little.
