    Coupe 1.8 De-cat gains

    Having a full stainless system fitted next week and im thinking of having a bolt in, bolt out de-cat.

    What gains can i expect and will it make the sound of the exhaust louder, as i dont want that ?

    What year is your coupe mate?

    Cost difference between an old coupe and new coupe is massive

    Noise difference, it'll be a bit more raspier

    Z series engines found in 2001 models onwards have a massive maniverter ( cat converter in the manifold ) and they're hellish expensive
