Loud pipes and earplugs

[midden]

If by loud you mean louder than standard.
As for earplugs you should never ride without them. Ear protection is mandatory in the workplace if the ambient sound reading is above 85db and most helmets are way in excess of that. I personally wear a pair of -35db every time I ride. They only cost about £8 for 50 pairs.

Yeah louder than standard........The ones people seem to fit so they can be heard by everyone and their granny.
I've only tried gel earplugs which completely seal the ear  so maybe foam ones will be worth a go
