    Default Basic Exhaust Question

    Hi,

    I'll start this by stating that I don't really know how the exhaust works.

    I am a newbie and have a 1.8VVT Vectra C. Last night, somebody kindly pointed me in the direction of this exhaust http://www.ebay.co.uk/itm/VECTRA-C-E...#ht_7705wt_956

    As I understand it, the exhaust components are : manifold -> cat -> "cat back section".

    Which components do you guys replace for performance? I haven't come across any manifold or cat upgrades.

    I will say again, I don't really know what I am talking about and am woefully out of my depth.

    I guess I am really after a simple explanation of the exhaust and which bits are worth replacing. It certainly looks like an expensive business! :-s

    Oh, and as of today I replaced my broken "life" rear bumper with an "sri" rear bumper so the exhaust is in the wrong place now (if you can picture what I mean).

    Thanks,

    Simon

    A chap called Tony Banks has offered to make me a custom exhaust at a very reasonable price. He seems to come highly recommended and this should save me a lot of hassle.

    I am still interested to know if you guys do anything about the CAT/Manifold though.

    Cheers. That looks really good. It looked enormous in the ebay pic but in proportion to your car it looks perfect.

    Is that system a "cat back" one.

    Cat back system but it did come with a Decat pipe...

    But under the new mot rules I thought to leave the cat on

    Or take if off, smash the insides and refit
