Many of the tunes are contributed by members, some are stock Triumph tunes. Triumph TORS (Triumph Off Road) exhaust add some sound and there may be a stock Triumph tune for them.
IMHO
Best bet is to see if there is a GOOD tuner in your area if you make changes to your bike.
Knowledge and caution should be used before changing your tune.
An improper tune can damage / destroy your engine.
Changing to 3 K&N or Ramair air cleaner also increases the noise, some like it some do not.
