Re: OFFICIAL: New 911 GT3 (991)
Agree with Macca, one thing to consider is with the full exhaust you might loose warranty. When I check with my dealer changing the center exhaust was ok from a warranty stand point. I am also interested ultimately by the full akrapovic or cargraphic only if the header and bypass muffler have no issue with warranty. Now that it got extended by a year, I really don't feel the immediate need. A friend with a 997 fairly brand new turbo got his engine in flame and it burned everything in the engine bay, cost 50k and neither Porsche not tech art want to bare the cost. So at the end for couple of more HP and db I am not sure it is worth it, especially with the extra noise of the full system. With previous 997 RS and full akrspovic exhaust some cars were not allowed in SPA
