The best off the shelf system IMO is the 3inch bore Magnex, with3.5 inch tailpipe. It's quieter than most systems, and being a 3inch bore, good for power.
My favourite zorst is the Power Engineering item in my Avatar. They are VERY VERY quiet at mway speeds - just what i like, but others dont. It burbles nice on idle, is incredibly well made, and looks the bollocks.
ive heard this about the scorpion about there being 2 kinds,the old is restrictive but the new ones arent,i had an old one which was restrictive and my mates just bought a erst with a brand new one on it and its just the same,does anyone have a scorpion on there car that does not have the restrcitive backbox on it,post a pic til i see it,and no cut out baffle pics either
also does magnex do a 3" bore,im sure its the mongoose that does the 3" bore for the rs turbo,never seen a magnex one listed anywhere and 3" bore are no good for power unless youve got enough power where its needed
