Just want to share this with you all:-
After contemplating buying a IC to Plenum Boost Pipe and DV i fell upon a local chap who was selling his Astra GSi and wanted a few pounds for his Regal Boost Pipe... so I thought 'Why not?'.
Now after fitting the Boost Pipe and buying a Collins DV... well.... Definately the Mutts Nutts.
I'm running the OE DV in tandem but it does not quiet down the Collins much at all so going with this set up for the mo, but will most probably fit a one-way valve some time soon...
All vac pipes i'm using are 3mm ID and i have by-passed the Rear BCS so have it piped direct from TB to OE DV and T'd in for FPR and Collins.
