If you lookat the picture, there's a small threaded hole which is at the bottom when the db killer is fitted.
A corresponding hole drilled in the outlet of your exhaust & a small screw/ bolt sorts it out.

I was hoping that wasnt the case - I don't want to drill a hole in my cans. 10 mins taking em off will do.

Cheers.

10 mins taking em off? - Have you ever tried removing then replacing termis with stock pipes?
PLEASE come & do MINE!!

yep, and it took me about 20 mins first time. I'm guessing now I know what to do, it'll take me less time.

My bike has just been MOTd with 50mm Termis on. No problem at all. In fact I think they rather enjoyed them, there was plenty of extra blipping of the throtle going on !!
U2U me if you need the dealers details.

From what I understand, db killers get 50mm Termis' down from around 118db to 95-97db..
Does anyone know how loud a standard can is in comparison?
Cheers.

Haven't the MOT regs just changed?? No probs as long as cans not "excessively noisy"??
