Hi folks, long time on piston heads but recently acquired a 07 911c4s, lovely car was initially buying it to replace the vantage but at the mo might be keeping both, I love the car but was thinking of upgrading the exhaust system, I advice or info much appreciated
Nice looking collection! As I understand it there isn't much more power to come via the exhaust route. Maybe you could get a handful extra with a high flow airfilter and remap, but I'm pretty sure Porsche have already done pretty good standard. Enjoy
