Hi all, Recently I bought a yellow 2014 Renault Megane 275 Trophy with 50000 km on the clock. The car is still under factory warranty and I am very happy with it. It has the Akrapovich optional titanium exhaust, recaro seats, rs monitor and 18 inch wheels. Can anyone tell me how much is the diameter of the akrapovich exhaust? I am also considering using R17 9j wheels with 255/40/17 tires with semislicks of 230/620/17 full slick tires for track days time attack driving and I am wondering if that is a good idea. Also do you think a Cobra sport cat 3 inch downpipe is a good idea or it is better to go with a 3 inch downpipe with no cat? Will the car require a remap immediately after I put decat or sports cat downpipe? For now I have bought a Wagner intercooler but I think I can drive it with the Wagner and with the factory ECU settings.
