    G,day all
    im geting a set of rockers from yt to complete my system on the old ecotec and it got me wondering today if when they have been installed will it give a different exhuast note over the stock setup? i mean these rockers are similar to putting in a new cam or something so it should alter the sound of the car wouldnt it? anyone who has the rockers installed have you noticed a difference? i know its trivial but i was curious:)

    it might deepen / ' lengthen ' the note but i think there would only be a small difference, i wouldnt know though, to be honest.

    Yes it will change the note, if you have extractors with a 2 1/2" system it will be more noticeable than just a system alone. As Patrio7 said it will be slightly deeper and a bit more "lumpy".

    it should, let us no if it does. porting and polishing heads made a significant not difference on my old motor.

    soz for stealing your thread,

    economy - yer depends how you drive lol, if driving sensible it did. was about 400 for the port polish an shave, then the head gasket kit (head gaskets rocker gaskets exhuats etc) forgot how much, an a fair bit of time.

    but was worth it

    no worries lol:p &thanks for the reply:thumbsup: so did it make a good noticeable difference performance wise? so far all i have on my car is a set of pacemakers and cai with k&n panel filter. i was looking @ fitting the YT rockers ,2&1/2inch & getting a chip! theres plenty more i could do at a later date but i will probably leave it at that:)
