All depends on how much your willing to spend i guess :lol: several companies do them. empi, bugpack, scat the general part companies really. Just shop around until you find some that suit your requirements or budget
Hi Paul,
I've put Jaycees on my 1600 from Cool Air, didn't come with any instructions, so just dont fit them this way!!!! ask me how I know. What a muppet, got home on the first drive and luckily I only did 2 miles, had oil dripping out the engine like water!! Anyway, after much swearing and difficulty, I can back up the claims to be able to fit these without taking the heads off. Turned them around and they do what they should, and look cool. Bit pricy at around £100 IIRC.
Good luck in your search, I'm well happy with these.
