Bonneville T100 2015 Aftermarket Exhaust Or De-cat X Pipe

Hi All,

I have a 2015 Bonneville T100 Black that I am looking to do some mods on. As always, the exhaust sound is dull so I am interested to hear what the better option is - New Aftermarket exhausts or De-Cat X pipes.

From what I have read so far, the De-Cat X pipes are only for 2016 up liquid cooled models. If anyone know of De-Cat X pipes for EFI models upto 2015, I would be grateful.

Second option is the aftermarket exhausts. I am happy with the looks of the original exhausts so if anyone can recommend a similar looking but more importantly U.K. road legal exhaust/slip ons then that would be great.

I am currently planning to do following mods:

1) Move mirrors to handlebars (TEC)
2) Change indicators and taillight with Complete Bolt-on Retro style kit from Square Deals
3) Retractable Gas cap from Square Deals
4) Front indicator relocation (using TEC bracket)
5) Move Rectifier (using TEC rectifier and horn relocator bracket)

 

Thanks steve for the info on "Cats". I was suspecting it as I couldn't find any option.
With the Arrows, I don't really like the looks of it designed for Bonneville and would prefer to keep with existing look of the pipes.
Would I need to change the whole exhaust or are there slips on that can be put on Bonneville T100 to improve the sound?

 

After a bit of research and looking around, I have decided to go with Dunstall as they seem to be loud, good and value for money.

I am assuming EFI remapping will be required for the new Dunstall silencers? Also, does this count as a modification on the Bike and needs to be disclosed to the Insurance? If yes, I am assuming the cheat insurance co's will want to stump up their premiums.

 

Thanks Tallaferro. I have just installed Dunstall exhausts and will go through your link to see how to stop wild popping.

 

Thanks Tallferro.

As always, the popping wouldn't stop with the remapping of ECU with Triumph TOR so I am going with your suggestion to block it with a 14mm ball bearing. I have ordered one over ebay and hopefully, fingers crossed that solution shouldn't cause any issues or damage to the AIS system. Longer run, I am planning to either have a stop valve or just remove it completely depending on how much time I can spend on the bike.

 

A quick update on the result. Surprisingly, I just remapped to 20505Map.hex OEM md5checksum which is for use with LCD Odometer - Use with Arrow 2-2 system, LCD odometer. Fuel up to E10. Minimum 91 RON (87 RON/MON) fuel. Previously I had mapped to 20500 map which is for Arrow 2-2 system but with E25 fuel and the popping continued. However, after tuning to 20505 which is for E10 fuel, the popping seems to have gone completely without any blocking or removal of AI. I have done first ride today to work and it seemed perfectly fine. Whether this will affect my mpg reading, I will know in a week or two.
