Part mod, part maintenance last weekend...
Swapped out the plugs, which look like the originals, but it's only just ticked 70k so that's to be expected...
Old and new side-by-side...
Upgraded the standard Cats for hi-flows... they make a lovely noise around 2k-4k RPM when accelerating, but when cruising on the motorway I can barely hear them, which is exactly what I was after.
Everything went to plan, but the higher flow on the HFCs seems to have upset the ECU and it's now a bit lumpy and/or hesitant on occasion, so it's booked in to see Jez at H-Dev for an UpRev in a week or two's time.
