Dunno what the hell that is ???
The 2007 header is built differently. If you look close at the photo above, you can see that the collector tubing is two parts that are press rolled together, and then the end is added. The catalyst can be put in before the end is welded in place, or before the two parts are pressed and rolled together - just like on a cat for a car.dr_gallup said:Devi - How do you think they install that? Looks like maybe they swage the end of the tube down after inserting the cat? Drill out the center then twist it tighter to reduce the OD & slide it out?
Should we make a full road trip project out of this if it can benefit others? Road trip to Birmingham? Consider going from stock to full custom in one shot or in steps? Just thinking..Devious said:The big restriction in the exhaust is the stock silencers. So the midpipe on the later bikes is likely not going to change this much - if at all.
I am under the impression that the 4 hp gain for the 2007 bikes is from the Arrow 3-1 system - not on the standard bike (this may easily be incorrect). The last dyno charts I saw for a 2007 model in a magazine showed the same power as the 2005-2006 models. But it is possible that even with the catalyst in the midpipe, the improved tuning (not much) of the later ECU may give the added 4 PS.
Until we see a member dyno his 2007 model we will likely not be sure about this. If you compare the early and late 1050 tunes, they are nearly the same, so I would expect the same peak output.
I do wish Triumph would change to the honeycomb catalysts though, we could do a lot with a good silencer on the stock bike. The stock silencers get HOT, and stay that way for a long time - compared to other silencers.
