Triumph Tiger 800 - Tuning - Exhaust

After much deliberation I decided to fit a Leo Vince Evo2 Stainless Silencer.  Why the Evo2?  Well I like the look of the silencer, it is slim - only 110mm
wide, cost was less than £270 and I really like the double mounting bracket.  The mounting will provide extra strength which is important on a bike that will
travel off road and occasionally bottom out.  I also like the fact I can use spacers on the double mount to fit the silencer closer to the frame because I
planned to fit the Nomada Panniers I took off my Tiger Explorer.   My new Leo Vince silencer arrived well packaged and it is well made.  I had wondered if
early Tiger 800 Exhausts will fit a 2015 XCx, on the invoice Leo Vince list the link pipe as specific to the Tiger 800 2015 XCx model, this implies that the
dimensions are different from early Tiger 800s.  
My Dyno runs were booked for 6 October 2015 but my rear ABS Sensor played up preventing me from switching off Traction Control. The sensor was
replaced under warranty,
Dyno testing was completed on 27 Oct 15.  I measured full and part throttle with both my Leo Vince and the standard
Why use the optional Arrow map?  Will I make some air-box mods? See my Tuning Summary and Tuning Air-box pages.
I think the Leo Vince Evo2 looks great on my Tiger, I went for the stainless option.  As a nice touch when the exhaust heats up the link pipe changes from bright
silver and darkens to match the standard Triumph down pipes.  Leo Vince provide machined aluminium mounts to replace the rubber mounts used by Triumph, they
also supply a 20mm spacer.  I decided to fit the Evo2 as close to my bike as possible.  I re-used the Triumph rubber mounts and I left the 20mm spacer out.  This
means my Nomada panniers can sit nearer the centreline which is great.
I have run my Tiger without the DB killer, the exhaust is definitely louder and deeper, not too bad but I do not like noisy bikes.  The DB killer extended 120mm into
the silencer, I cut 110mm off and my shortened DB Killer is going back in permanently.  I took my Tiger with the Evo2 + Arrow Tune on a long trip round the Lake
District.  The Exhaust is louder (and nicer) when accelerating, on the cruise the sound is muted, not too much droning.  Performance was good and the fuelling
seemed OK.  As a bonus my Tiger is now much harder to stall.  Acceleration from 2,000 revs in any gear is more rapid and I have no popping or banging on the
over-run. Fueling may be a bit more fluffy below 2,000 revs but nothing to worry about.  Overall my Tiger 800 XCx is great to ride with the Evo2 + Arrow tune.
My only moan is that the 8mm nuts supplied are not self locking.  The Leo Vince has Carbon hangers which can easily be crushed if the fittings are overtightened.  
So IMO self locking nuts + threadlock are essential.
From the rear with the Evo2 fitted my Tiger 800 appears much slimmer. Top right of my numberplate is now melting nicely
