Milltek 3" downpipe AFTER stage 1 remap

Right guys I'm currently stage 1.
I'm on the road to stage 2+ so will be fitting the required parts as I go.

So, in the mean time, will I be safe running the 3" downpipe on a previous stage 1 map? With having it tweeked?
As I've heard it may create boost spikes due to the increased flow.
I will be running it until I'm ready for the stage 2+ map, but that won't be for a while. Thanks

Currently running a full 3" exhaust system which was put on AFTER my Stage 1 map...no problems at all...apart from a mysteriously decreasing average mpg :fullmoonface:

Did you feel a noticeable difference even without a map tweek?

Turbo definitely spools faster and car seems to have a bit more torque, holds torque a bit better too....maybe it's mostly placebo but it's a definite improvement!

+1 to that, definitely picks up better and pulls stronger apart from my misfire, the ecu will adjust accordingly so i wouldnt worry too much about running it with it on but id make an effort to get the map adjusted after a while

You may find that you get a light on the dash after fitting the downpipe. Removing the light is part of the stage 2 remap.
