ktr

Hello everyone, I have a ktr throttle body mounted on my Clio 2RS 172 and I have a question concerning the 4 screws under the injectors (see attached pictures). When I want to mount my injectors, the injector mounting clip comes up against these screws. Ktec has confirmed that these 4 screws...

First post here... since having a 182 I bought it the other week and am now a proud owner☺️ The exhuast is quiet though, it has a ktr not sure what one but it has a cat and silencers and isn't really loud at all. Would a decat make it louder?
