just wondering if someone could help, I have an ED30 and have purchased a decat pipe and full aftermarket exhaust, im getting them fitted tomorrow, but im worried if fitting the decat pipe will do any damage to the engine, until i get it mapped to stage 2+ to map the sensors out, there are two location points on the decat pipe for the lamba and 02 sensor i think this is correct, and also does anyone know the thread sizes of the sensors just so i can make sure there the right size on the exhaust, any help would be appreciated.
