There’s a guy on YouTube called ‘Last humans garage’,he has a 7.5 Gti and has done all sorts of mods to it.
He has done his exhaust tips and they look great.He originally bought some ‘Burger tips’,which slid on-or were supposed to-they are made for mk 7,not 7.5 which has a wider pipe.
He got round this by grinding off the tips,this enable the burger tips to slide straight on,I really liked these,it made the exhaust look bigger,without looking daft.
But for some reason he didn’t,he had another back box and sprayed the tips on that.
