.... Goes to show those on this forum, that previously have 'poo-poooed' my rants about the value of loud pipes for 'performance' gains...
These guys (thunderbikes) seem to be much more 'professional' than the rest.... Although all of these pipe manufactuers and Modification 'hawks' need better proof to back up their marketing rehtoric...
It's the simple things, like a proper windscreen/fairing or in your case, removing the snorkle, that will provide the 'real world' performance that you're after.... After all, what good is Horsepower and Torque if these are only available in narrow regions or spikes in the RPM curve???.... This goes against the Triumph design philosophy of 'Continuous Power' at all RPMs.
If an engine design can generate huge power ala. the Rocket III, then the loudness of the exhaust note is "mute" (pun intended).
This is the smart way to go..... change ONE thing and ONE thing only, determine if there is a qualitative improvement... If there is, then move on, if not, go back to square one and try a different approach.
Daz....
I'm personally happy to see that you're at least trying to qualify the marketing rehtoric... Unlike most of the folks on this forum, who seem to just follow the 'leader'...
But then.... You're a Speedmaster rider... I should expect this mentality... After all, It's was your Design/Quality and Asthetic sensibilities (And you're sense of Triumph History...) that has drawn you to the Speedy!!... I'd like to thing I share those sensibilities and independence of thought.
