Mate, pulling the old exhaust apart to get it off and bolting the dump pipe up to the turbo is where most people come unstuck. If you do not have a deep socket set, good quality ring spanners and some helpful bits in the shed then take it to an exhaust shop and pay them to do it. Every time that I do an exhaust changeover or fixup on my vechiles, I swear next time that I will take it to the exhaust shop to have it done.Is it a fairly easy swap in for someone with not much mechanical expertise (me!)?
Would it need a tune immediately or could I at least book it in and drive it for a couple of days?
