Just fitted the D&D slip-on reverse cone megas on my 2004 BA and the sound is awesome. Had TOR shorties on before which suffered popping and backfire on decel.
These TORs were OK and loud but sounded like the Triumph Scrambler- a bit "barky"
However , followed Pat's carb rejetting guide ( really useful) and swapped out from stock 120 mains to 130 and changed the pilots from 42 to 45.
Now , no backfires , hardly any popping on decel , a great sound and great looks.
Louder than the TORs , and wakes up everyone in the vicinity on start up.
Expensive considering the shipping charges but worth it, so thats my Christmas present this year!!
