    Courntney/Regal precat replacement+Standard system??

    As title - will this configuration work? :?:
    If so what could be the likely results - I know that the backbox is probably the most restrictive part of the exhaust system so it would be better to change it all - but i'm just trying to look at other possiblilties!!

    Any ideas??

    The pre-cat is the most restrictive of the system so it will work well!

    I've got a milltek pre cat replacement on order (I've been waiting a few weeks now though! )

    Do it - will spool the turbo quicker, and make a big increase in noise. Worth it though

    Nice - where do you recommend - Regal have it - but is it worth having them fit it too?

    Hmm - i'm wanting to do all my mechanical mods and give the ECU enough time to adjust and optimise before remapping - e.g steve(SRI-T) is running @ about 221bhp on mechancial mods alone. I reckon that once i have my exhaust sorted and then remapped too i should see 250bhp?? with OE turbo and IC
