    Aftermarket Headers...

    Anyone actually run aftermarket headers on their beat?

    If so, did it delete the cat/o2 sensor?

    What brand/model are you using and how do you like it?

    Thanks Maiku. How many YEN was the header?

    Was the cat specific for the Beat, or sourced in Canada?

    Do you have any dash lights on (warning lights)? If all warning lights are off, then I'd imagine they must have put a new O2 sensor in?

    The header was 17,500 yen, quite a good deal.
    My mechanic just took a universal cat for mid-size sedan and crammed it in, along with a new bosch O2 sensor
    No codes related to the cat, and my emissions testing was ridiculously low

    Good to hear. You don't have the sellers name or brand of header? Most headers I'm looking at were about 30K yen.

    Do you have aftermarket exhaust as well with the header? If so, which one?

    Any power difference with the new headers from stock?

    Along with their center mounted exhaust.

    It was a generic seller, the sale expired so I can't see who the seller was
    They like to refer to it as an exhaust manifold instead of a header

    I got the HKS dual exhaust for the beat

    The one thing I've noticed with the stainless manifold on my AZ-1 is a dramatic increase in engine bay temperature - stainless pipes just don't keep the heat in as well as the original cast iron item although the exhaust flow is better. I don't know if this would be much of a problem on the Beat but thought it worth mentioning.

    It's a major issue on the AZ-1 - the air outlet pipe from the turbo runs very close to the manifold and the air inlet temp has increased dramatically. I just wish I'd had it ceramic coated before I fitted it, they dont stay shiney for long anyway.

    heat-wrapped mugen header with stock cat and mugen exhaust on ours. sounds very nice, quiet up to a point and then howls nicely.
    had one of these fitted too but removed it as my other half grumbled about the smells coming into the house when i was backing up onto the drive

    Yah, tell me about the sound.
    I get a bit of droning around 4000 rpm with my headers, it gets louder as I add more gas
    Could also be the exhaust
