that 90db is at a certain point in the rev range as well, or it used to be :P, hate to think what they would say bout my motor bike since it 92db from the factory and it was built in 1992 :D
also just having a quick look at the lukey website they have 4 different mufflers.
Ultra Flo Muffler, Turbo Muffler, Race Muffler, Original Glass Pack
i think it more a personal choice which one you go with if you get a lukey,
i personally have never used a lukey muffler on any of my cars, but i have heard only good things bout them :jamie:
