    Astra mk4 centre exhaust section

    Hi,
    I was wondering if anyone knew where to get a cat replacement centre section for a 1.6 16v MK4 and if so at what cost?. I can only find a cat back section at the moment for about £75.
    If i went for the cat back section then what kind of BHP boost could i expect (if any)?. I currently have a standard exhaust apart from a Peco backbox.

    Thanks

    Welcome along.

    Sounds like you need a Remus Race pipe - I think you can get them off LMF.

    One of our local members got 140+hp out of a 1.8 with just a Remus pipe and Irmy back box. That's up 15+hp from standard for his engine. You should be looking at least 110hp or there abouts.

    Sounds good. I have found a Remus Racing Centre Section (cat back) on ebay for £80 inc postage.
    Was pretty set on getting it but thought i would look around for a cat replacement pipe instead. Cant find one tho!.
    If no1 has any alternatives i think i will get it.

    Thanks.

    btw. Nice forum. From what ive seen its friendly and helpful!. Thanks again.

    What year is your car?

    If it's a 2001 or younger then the catalyst is part of the manafold, so you'll be needing a replacement manafold as well to get rid of the cat, along with a remap to allow the ECU to run the engine with modified lambda values.

    Its a 2000 W reg. I cant afford that kind of modification at the moment!. So i was wondering if the Remus section would make a difference or just noise!. If i just replaced cat back would i still need to remap the ECU?.

    Thanks
