| If its carbon termis on the SP5...then I think no way...I think people have mentioned standard cans even failing at Donny on Dukes. Standard cans are rated at 98dB I think...so even they are iffy.
I personally wouldn't take the risk at donny on quiet days anymore, I don't fancy being thrown off halveway through the day or not even making it out on the track...they do enough noisey days now anyhow. |
