Hi all, just wondering what is the optimum size for downpipes from KO3/KO3s turbo's with remaps running 200-230bhp.
Thought 3 inch may be better, as youu could shift gases out quicker, but is the 2.5" better cos it holds the back pressure better or what?? Little confused. . . any one who knows???
Also, would a Milltek sports cat be better over a Blueflame sports cat, as Jabbasport are trying to tell me that i want a Blueflame, and not sure if I do.
I want what's best for power!!!!!
