    Simple things to do to a 2.2 SRi Astra? Tuning etc..

    Hi, Dad has a 2.2 astra, As below..





    (Need new pics!!!! Posted these so many times)

    I have fitted a vectra c intake pipe, de-restricted the airbox and have a pvd/cs/pipercross panel filter coming tomorrow!

    What else can i do to fiddle with the engine etc? Kinda fancy a remus middle pipe for it! What do they sound like with the irmy backbox?

    Thanks

    PS - Any other exterior things etc will be concidered!

    Apparently, on the 2.2's, the precat can just be knocked out. As in, if you take it off and shove a broom handle in until is all clear. that will release some ponies.

    The precat's worth removing, but that looks like a late 2.2 so it might not have one.

    Loosing the irimy back box for something less restrictive would help too (added to the remus cente pipe)

    Wrong, you need to stitch drill it out very slowly - see the how to's for all the gen

    The irmy back box will raise a fortune on ebay too so would probably pay for a new less restrictive box.

    Drill loads of little holes round the edge, and then join them up so the centre "plug" comes out
