Not even sure Calsport stock them anymore. I think the part number required is V-TUV003/1. I've got one for your exhaust but can't part with it incase I ever go to a track that needs it...all I can say upto now is; that slip on doesn't need its baffle at Oulton Park.
Part number isn't stamped on it by the way, I'm just going off what it shows on the schematic diagram on the Akrapovic website.
thats great thank you Calsport have this listed not sure if its a generic image https://calsport.co.uk/honda-cbr-10...gp-megaphone-s-h10so11-t-recommended/v-tuv158 ebay has this https://www.ebay.co.uk/itm/154459544877?epid=1939149373&hash=item23f6819d2d:g:8wMAAOSw0yph8BDQ
That one direct from Calsport isn't right, it's a different number and is for the megaphone. The ebay one (which is still Calsport) looks right to me. Just email them to confirm though. Are you going to run it all the time? I don't find this exhaust too noisy even without the baffle personally. Are you running stock headers?
Just want to try it with the baffle and see the difference better to have it just in case. and keep everything original
I found it very tricky to get the baffle locking bolt to line up, I ended up removing the silencer and doing it on a work bench. I don't bother removing it any more, even if it's a "noisy" trackday I just leave it in.
