My V1 Gruppe-S headers have cracked, where one of the nearside cross pipes enters the collector. The same day that I finally got my Power FC mapped for my new 2.5 install . Its running 1.3 - 1.4bar is this too much for the Gruppe-s headers or am I just unlucky?

Unlucky yes but get the crack tig welded.

 

My V2's and helix flex up pipe have stood a pounding @ 1.5 bar no probs

mind did exacly the same, you can weld them up. Part of the problems is the welds are very thin and have no filler material.

 

OK thanks everybody, the ride home after the mapping with Paul at Zen Performance was absolutley fantastic by the way, was looking forwards to a weekend driving it, but seem to be back under the bonnet again .
