I have a 2013 C6 Grand Sport 6-speed. Im looking to put a more aggressive axel back exhaust on it. Im not too worried about drone...as most of the time I turn the radio off and just listen to the symphony of an American V8. I've narrowed my selection down to the Corsa Extreme system and the SLP Loudmouth 2 system. The SLP is quite a bit cheaper but I'm a little concerned that it may lack quality and that the low exhaust flow restriction may hurt the longevity of my motor. The down side to the Corsa system is obviously the outrageous price. Anyone have any personal experiences with either system and can give me some inside advice? Thanks!!
