Hardin Mufflers

[Blue Thunder]

Anyone tried these mufflers? Were you satisfied with the noise reduction and minimal power loss? I'm looking for noise reduction on
650hp supercharged engines. Are these a good choice?

Dave, those mufflers will take the bark out of your engines, are you going stealth?!

How much HP are they good to without hurting?

Yeah, I'm growing tired of the dry pipe crackle. Plus I will be able to hear the blower whine better :sifone:

Do you have any specifics Bill on db reduction and hp losses? Do you sell these?

For 650hp i would suggest these - 410-283450 Cyclone Series Clamp-On Silencer.
