    Default silencer removal... Thought?

    Been googling away for a while on this one.

    Want to keep my cats in place but want a little more noise.

    Can get an exhaust made up from the Y piece back with no silencer.

    Has anyone had this done?

    How does it sound?

    I did this with my Vectra VXR and it sounded great... But that was a v6 not an inline 4

    Should think that you will go through a large amount of earplugs

    just cant see it being that loud from a 4 pot.

    The Vectra sounded awesome with the rear boxes removed (not intrusive at all)

    Lots have people have gone for this and said it was a worthwhile mod. Think korkyy did it and then got the secondary decat afterwards. Maybe try asking on the astra j vxr owners club on facebook, it's more active than on here.
    You may as well do both the silencer delete and secondary decat. Still passes MOT and thats at Vauxhall.
