So now for the fun stuff, the re-assembly. I did some rough measurements on the old outlets, and cut three tips from a tube of 44.5x1.5mm SS316 tube. I cut in 45 degree tip angles to try and maintain the OEM look, but to be honest it probably should have been a steeper angle to more closely match the OEM tips. These tips were then TIG welded into place. This process took the longest of the whole build, but only because there were big gaps to fill and I did not have a roll of SS MIG wire, only TIG filler rods. Closing big gaps with TIG machine is a TEDIOUS process!
Once the tips were in, it was just a matter of rejoining the two halves, which went smoothly, and then a quick respray with High Heat paint. From here, about 45 minutes to strip down the necessary bits (Seat, Seat Fairing, Pillion Handle, Tail Piece and old muffler) and have the new unit in!
And the result? I have not remapped the ECU yet, but the sound is much deeper and definitely louder, and that triple just sounds fantastic at around 4-5k RPM!! Also get some lovely pops and burbles on the over run, with a loud pop about 5-7 seconds into the overrun. Will try post some Audio Clips or Vids soonest!
Next challenge is to get the ECU remapped with Tune ECU. I bought the cable from the TTP website as per recommendation from another post on this forum, and followed all the steps on the TUNE ECU for dummies post, however when I try connecting I get an error "Could not connect to ECU". It tells me to check the cable and connections and to turn ignition off and on, but I keep getting the same error even though the PC can see the cable.... BTW, I ordered the cable on a Friday afternoon and opted for the more expensive courier shipping as our Local postal service is pathetic, and the cable arrived the following Monday afternoon!!
Anyway, enough of my long post, enjoy the pics and hopefully soon some audio!
