if the scorpion decat doesn't have the correct bend (90% of the decats don't have the bend in them) then that will cause the tailpipes to sit off to one side
Any up close pics please? Did you have it fitted locally or at Yozza?
Will get some Close up pics 2moz.
thats the decat pipe (non YS) causing that, seen it loads of times, try slackening off the spring bolts slightly
