i am goin 2 be fittin a downpipe 2 my 54 plate wrx and just wonderd if any1 else had done it themselves so i know exactly wat 2 do and wat i need any help would b great

 

Easy mate,
Intercooler off,
Turbo heat shields off, some 10mm bolts a bit fiddly, there's a few.
Remove the 5 nuts that fasten pipe to the turbo,
Remove oxygen sensor,
Remove 2 nut and bolts from rest of system,
Fit new pipe
I cut the lower section of my turbo heat shield as it wouldn't fit over
bell mouth downpipe.

Hope this helps
