Triumph Daytona 955i 2002 – Wolf Under seat Exhaust Fitting

After a looooong wait my Wolf under seat exhaust turned up (Wolf delivered it 6 weeks late!). Fitting was fairly straightforward as long you follow the instructions step by step — it did take up most of a Saturday afternoon, mostly due to my pitiful knowledge, sausage fingers and lots of head scratching. But the finished article is great.

triumph-955i-ce-sideIt looks superb IMHO and sounds… well… it now sounds like a real motorcycle!

The exhaust is delivered with the baffles as an optional extra. I fitted them because the unbaffled sound was a little harsh and actually prefer the noise level with baffles fitted. Very little difference to tell the truth but the baffled version sounds a bit deeper – which is my favourite type of noise.

It sounds *slightly* louder than the OEM Triumph Race can *but* shouldn’t offend Plod when at lower revs. It has a terrific deep burble and howl sound when it’s opened up. When you roll off the throttle it pops, spits and snarls like a wild animal.

I recorded a short video with full sound if you want to listen to the exhaust at tick over and removed the pillion pegs on my bike, but there is no reason why they cannot be refitted.


The Wolf was £900 with the anodised titanium end cans. End cans come in stainless, titanium and carbon flavours. The system is all well built and looks like it will stand the test of time.

Fitting was a bit of a pain and certainly took me much longer than the 3 hours recommended in the instructions.

Basically fitting means:

  •   taking all the fairings off the rear
  •   removing exhaust
  •   disconnect electric (battery, alarm, ecu, fuses, relays, indicators etc..)
  •   remove plastic water header bottle
  •   remove plastic under tray
  •   drill out the seat lock (which is riveted in) – no problem because it can always be *screwed* back in if you want to revert to OEM pipe.

then fit all the new stuff:

  •   it Wolf metal battery box
  •   fit battery and ECU into battery box
  •   fit horizontal Wolf heat shield (across top of where pipes will be)
  •   fit Wolf metal water header bottle
  •   fit all electrics back to frame and heat shield
  •   fit pipes and exhaust canisters
  •   fit bodywork back on….

I found the Wolf Underseat Fitting Instructions a little ambiguous, they don’t clearly explain what all the components are, but with a little patience and trial and error – it all fits simply enough. It wasn’t a difficult task just time consuming and detailed.

IMPORTANT: Pop down to your local Triumph dealer and get them to load the ‘Triumph Race Tune’ into the Bike ECU… Jeeezuz!!!!! What a difference. Combined with the under seat exhaust the Daytona is now riding like a completely different bike. Flat spot has vanished.. Power seems to come on early and just increase throughout the entire rev range. My seat of the pants estimates would say that it feels 20% faster everywhere.

The exhaust howl just sounds FANTASTIC.
