Can anyone help me with the following - I have a 2017 Street Twin fitted with Vance & Hines 2:1 SS high exhaust system and unfortunately, the bike fell over last week on a shingle drive and the silencer has been damaged. I have just found out from the local dealer that this exhaust system which was made for Triumph by V&H is now obsolete - really disappointing to hear so I need to get the damaged shingle rash on the outer shell repaired. I managed to remove the dB killer from inside the silencer, however I can't get the carbon fibre end cap off. I removed the 2 screws on the of the unit which hold the cap, however this has not helped. The big problem is there is nothing to hold onto and there is also no internal lip or recess inside the silencer that you can tap against with a long punch to help remove the end cap. I then contacted V&H in the USA to see if they could recommend a method to remove the end cap and they came back and advised the following: "Unfortunately, Triumph wanted these mufflers to be extremely 'tamper resistant'. So the way the muffler inside was pressed into the muffler body, makes it extremely difficult or nearly impossible to take out. We do not have the Blueprints of this system anymore. Sorry I cannot be of more help" Has anyone found a way of removing the carbon fibre end cap? Also, if you leave the dB killer out, will the engine run ok or do you need to get the tuning redone? Cheers
Hi Syd. I'm not sure if it will be the same on you V&H but with the Arrows you have to apply heat with a hot air gun or hair dryer.
I was just thinking similar thoughts. What about warming the whole thing in the oven for a while. Or going the other way and sticking it in the freezer. The materials will expand/ contract at different rates so a little playing around altering the temperature might help.
Thanks for that - I will give it a try. The carbon fibre cap should be ok with heat, therefore it should work
Thanks for the tips - Do you think it would be ok to leave the dB killer out of the silencer without causing any issues with the tuning?
The way i would attack this is locking it in a vice or similar heat the can not the end carbon tip. That hole in the carbon tip i would replicate the other side an put a bar through it and gently ease it of. Just the way i would do it. Joe.
Syd The bike should reset its self and recognise the changes. If not get it mapped or replace the DB killer. Joe.
Give it a try and see how it feels. The lambda sensor should cause the ECU to compensate a certain amount for the change in back pressure, but of course it would be best to get it remapped on a dyno.
