what problems if any will 2 x pipes have?
I want to be able to put the original cat stock unit back on when I need to, so I will use the Basani the rear kit - also an x pipe, to avoid cutting into the original.
Are there any un wanted side effects to having 2 x pipes arranged in this way?
Is there an altrenative single x pipe sytem/arrangement which can go direct from the headers to the mufflers ?
