Anyone know how restrictive the standard cat back system is?
I initially just intended a couple of subtle mods KN panel filter, ECU spacer, Decat and downpipe and a DS remap as i want to keep the car standard looking, outside and underbonnet as i have no intention of ever getting rid of the car.
But as time is going on im getting the urge for POWERRRRR! you know how it is!!
