Hello good people. My S4 is still in the company that will homologate it for Spain. The car has been to ITV (Spanish technical control), who refused it because there is no catalyser on it. I plan to put a sportscat on it, but for now homologation is my first concern.
Since the car is at a spot where I am not allowed to travel (thanks to the COVID regulations), I can not measure anything. I mean tube diameters, and dimensions, since there is not a lot of space there.
SO, if anybody can give me the dimensions, or better a brand that sells one that will fit (and is homologated), or even
