I'm sure this has been asked before but I'm after advise/opinion on after market exhausts. I've heard the Sharkwerks Bypass system is good as you can still use the 'Sports Exhaust' button to open & shut the valves as it only replaces the standard back box. I'm not after a stupid loud system just something with a bit more 'something' on down shifts. Also does it effect your Porsche Warranty? Thanks in advance.
