Thanks for the advise...

Stephan,
The stock R3 Touring is very restricted in the ECU in stock form. This is easy to change. My dyno reads around 13% lower than Dynojet dynos, and we normally see the stock R3T put out 85-87hp and 130-132 ft-lb of torque. After removing the restrictions in the stock ECU and mapping it in on the dyno, we tend to see 115-117 hp, and 138-142 ft-lb. [A very significant increase in horsepower and torque.] We tend to see significant gains in cruise mileage as well 33-36mpg at 80mph+ and 39-43mpg at 70mph.
The TORS (Triumph Off-Road System) exhaust really does not produce any more output on the R3T than simply drilling a hole in the baffle in the stock exhaust. The real exhaust restriction is in the diverter box under the bike, in front of the silencers. This is where a custom replacement Y-pipe can help.
A K&N filter under the seat does not show significant gains. There are gains possible with going with three RU-2780 filters under the airbox - especially with full aftermarket exhaust systems.
I have attached a graph of different R3T models tuned with different exhaust and air filters. Dashed lines are torque, solid lines are HP.
Red - As delivered with TORS exhaust and K&N filter under seat - 86.9 hp, 131.1 ft-lb (stock exhaust will be a bit less)
Blue - After mapping with TORS and K&N. 116.8 hp, 142.6 ft-lb
Yellow - Stock air filter and exhaust - 1" hole drilled in baffle. After mapping - 115.1 hp,137.68 ft-lb.
Green - After mapping w/ D&D slip-on silencers, triple RU-2780 filters under bearclaw. 115.6 hp, 138.9 ft-lb
I hope this helps. Please call for more details,
