Hi Guys I recently bought a used HKS SD system to refurb & put on my classic.Main reason was for it's free flowing qualities.Not for a loud noise.Over the last few days I have read that they are as loud as a Blitz! If that is the case it's going.Pronto.To old for all that malarkey.Any thoughts on this?
Thanks

 

i had one on my classic wouldnt have said it was as loud as the nurspec thou... i had that prior.

 

Not as loud on idle but a very loud bark on throttle. Certainly isnt quiet but then very few 3" systems are.

 

Thanks for that fellas.
Think I'm gonna get rid.Will be too loud for me I think.
