As above I need a quiet 3" backbox as I have a 3" hks hi power and it's too loud for what I need. I was looking at the magnaflow oval boxes and the vibrant ones, does anyone have any experience with these or any other one?
I have a 421 manifold, sports cat and a 12" mid silencer.
Any help would be appreciated cheers
