Had the Termis fitted to my 1200 R from new by Ducati Glasgow and the db killers are still wrapped in tissue paper. Love the sound.
Took the db killers out today and went for 100 mile run. F**K me it's loud. Walking up to the bike on my drive I felt it through the concrete from about 10 feet away lol. It's a bit too loud. Definitely no chance of stealth riding without db killers. Have put them back in cause after 60 miles was getting a headache. Mine sounds superb with them in and barks and bangs and pops in all the right places. New headlight fairing seemed to reduce windblast a fair bit too.
