Hi as I am about to move to an apartment with an underground car park, I am looking to change my noisy silencer (so not to upset the new neighbours) can anyone suggest a good new silencer that will go with my tuned 500 L fitted with a Weber 40 & lumpy cam, I am sending the weber to be stripped & cleaned (full Service) would a standard silencer reduce any performance? or is there a quiet sports “looking one” that’s not noisy? Any suggestions appreciated. Barry
