I do not know if the flashers are removeable but there are screws in them so maybe.
I was going to get a WSB type exhaust but my Termi eventually arrived so i just used the standard light but if this does not sell i am still going to fit it anyway as it looks good.
Got your u2u but no email, although i have seen the seat on ebay i still do not know if it would fit the mono subframe but really this too was to go with the WSB type exhaust that i might still buy anyway and fit it to my new cat free link pipe and use the Termi ecu and free flow air filters.
