    Help Or Advice Please Anyone...?

    I was looking at a Cat Back exhaust system...

    But i have a Mk 4 2004 astra 1.6 twinport hatchback.... And i though the cat was in the manifold?

    Is that correct.....

    So if i was looking at a catback system, would the cat need to be removed from the manifold... or does it stay in and then the system just replace the original exhaust system from the downpipe?

    Any help please,

    Thanks

    the cat is in the manifold yes. a cat back exhaust is exactly what it says it is, it goes from the cat, back so no need to remove it

    so just leave the manifold alone and fit the catback system from the down pipe?

    Will sound like a right noob..... but what diff will a catback make...? as i thought it replaced the car in manifold and had a replacement cat further down the exhaust?

    Is it worth goin for a Catback...?

    will give you a few more hp, you may notice a bit more acceleration and a much nicer sound. it definitely worth it in my opinion, better than going for just a back box or just a race tube

    ive got a backbox now.... but no noise difference atall really........

    If i go for a catback system..... if i get one with the center silencer, will it still have a louder noise than just a backbox, and will it be a decent noise...?

    Or get one without a center silencer?

    most places will be able to customise a certain noise for you. wether you want it quiet, loud or louder further down the rev range.
