Are the relentless ones that are around £200 worth the money, are they a decent upgrade or prone to cracking.

Only asking as I'm breaking an S3 and was planning to sell the KO4 kit complete but the standard manifold i have is cracked (and the gasket was in 3 pieces - so that might of explained the gas escaping noises i was getting) and i have a BAM in my mk2 golf so i could use that manifold for the kit id sell and buy a stainless one for my mk2.

cheers
 
Pro4 is the 4th version of the manifold, rtech have dyno'd a few and they look good.
Sam Bryant seems to be looking after customers.
There's a relentless group on facebook dyno's and pics are on there.

The pro4 is made from schedule 10, welds fully penetrated and using a turbo support bracket they look good.
 
the welds are'nt fully penetrated. Not on the one I saw. The step in the pipe below is at the outlet of the Y join into the outlet single pipe.

If you have a choice of v1,2,3 or v4, v4 is made from thickest material from them so far.

38mm internal pipe diameter at exit into turbo flange, turbo inlet is 40mm
