Dump pipe
If you are talking about the DPF dump (race) pipe and not the cat dump pipe I have just done it. Makes a noticeable difference to the horsepower instantly and runs a lot quieter too. Can't give you any fuel figures yet but will post when I have a few to compare with the original system.
A word of warning if you are going to do it yourself!!!!!!!!!!!!!!!!!! At the rear of the new pipe, on the inside of the curve, is a threaded hole where a coupling for a flared pipe screws in. This is the only fitting which does not come off with the DPF. BEFORE you fit the new pipe run a bolt or tap (14mm X 1.5 pitch thread) through the hole.
When Chip-it coat the pipe this thread gets dags in it and the original fitting doesn't screw in. ( I rang them about the problem and they are aware of it, but don't tell you). Would have been nice to know befor I got caught on a Saturday afternoon around Xmas, and by the way Gasweld have taps that size for $16.50.
