    Astra 1.6 16v SXI 4-2-1 manifold

    Im thinking of investing in one of these... has anyone got one on theirs??

    Have you felt a difference???

    I used to have a Saxo VTR and I bought a 4-2-1 manifold for that.. made 118bhp with a couple of little bits.

    i imagine coupled with a full sports exhaust and a good enclosed induction kit it should be good.

    Z16XE is 98bhp/113ftlbs standard. You'd likely see 110bhp+ from just the catback - overall these engines are mostly strangled on the intake side and not the exhaust.

    Believe what you wish, but with catback and Vectra intake my Z16XE hit 117bhp/131ftlbs a couple of years back.
