    First couple of modifications

    Guys Ive just read this post by andyastra16v

    http://www.astraownersclub.com/vb/sh...d.php?t=196289

    im not expecting any great gains, just a few more bhps, torques, and to hear the sound of my engine breathing.

    been thinking of upgrading my the stock intake and exhaust. I have in mind the K&N 57i cone and a ?cat back, to start off with.

    Should i only bother with derestricting the box and using a panel filter? (also adding the vectra intake perhaps) is just a cat back good to start off with?

    As ive never tried upgrading such things on a car, im not familiar with the complications that can occur here. Can anyone give any helpful information about the kind of problems to watch out for? e.g urgent need of remapping..

    cheers

    I don't rate cone filters. always had issues with them so would upgrade the existing panel filter and derestrict the box. with the veccy intake.

    This is just my personal preference and plenty run cone filters with no issues

    No to the cone lad... heatsoak!!... best bet as gsi10 says or going for an enclosed one like bmc carbon intake, or like me think about the dbilas jobbie.
