I've noticed bugger all in terms of performance improvement though. Maybe my Stage 1 map needs tweaking a bit.

Really? I noticed an immediate improvement when I had a full Powervalve fitted (even made the clutch slip). That was on the existing Stage 1 R-Tech map. After Stage 2 it felt like I gained the same again. In fact, from memory it went like this:
Stage 1 - 243bhp 296lb/ft
Stage 1 & exhaust - 260bhp 320lb/ft
Stage 2 & exhaust - 270bhp 345lb/ft
You should definitely feel some gain from the downpipe. As I understand it the vast majority of the restriction is from the downpipe/cat and not the catback section. But maybe that's not the case after all? What downpipe is it?

It pulls a bit more vigorously to the redline than it used to, but everywhere else, I'm not really detecting much of a change. I think the map probably needs a tweak to be honest!
The factory DP is awful! Removing the cat material is only a third of it's problems! I'm amazed Edition 30s make 300hp with that thing!
absolute:
Sweet. Can I be added to a list or something? :)
Interested in knowing what options are available.
