    As in recommend other modifications?

    If you already have headers and a catback... and getting a CAI... then i would be looking at some high ratio roller rockers... I think they are available for the alloytecs... could be wrong...

    What are you trying to acheive?

    you want a different note while minimizing power? fit a quarter inch straight through exhaust.

    that means you have the 175kw motor.i'd just look at a set of pacemaker extractors and a k&n in the airbox then a 2.5inch cat back and dyno tune.

    i think what the fello is saying he has an my06 vz which has the ve update alloytec with euro 4 emissions at 172kw,

    theres not much differance in the motors beside a different timing chain setup and a couple little things,

    glaze was only on the my06's but there definitely was more than 50 made

    I didn't mean minimize minimize. I meant like gaining no power and losing non. I couldn't care less for more power, I just want something difference to the monotonous quiet of the standard exhaust.
