    Righty im planning to change my exhaust system as i've been told my current standard one on my 52 plate VTR 1.6 is knackered.

    I want to know what my options are for replacing the system? I think i want to put in a 4-2-1 manifold, should i do this at the same time?
    I know nothing about decat or cat pipes, whats the adv/disadv of both? How much am i looking at for everything?

    please help!!! cheers

    What have they told you is knackered and what is your budget?

    the 'exhaust' only from a quick look, proper inspection on friday.

    Budget as low as possible really, probs around 150/200.

    well a cheap 4-2-1 manifold will cost £150 alone but your oil filter will have to be converted to a mk1 filter unless you buy a more expensive manifold which will clear your manifold

    exhaust wise your looking at £200 for a decent center section and back box

    if you de-cat your car this will release a bit of power

    on early mk2's the cat is under the car so you would de-cat it buy buying a de-cat center section but if you have a later mk2 vtr then the cat is in the manifold which means buying an after market manifold such as a 4-2-1 or 4-1 manifold

    4-2-1 manifolds are better for low down power and 4-1 manifolds are better for power higher up the rev range

    if i was you id just buy an exhaust like the kam racing exhaust
    http://www.kamracing.co.uk/index.php...vts-01-04.html
    or a saxsport
    http://www.saxsport.co.uk/

    and a cheap 4-2-1
    http://www.kamracing.co.uk/index.php...n-saxo-8v.html

    but obviously de-catting your car will fail an mot so it will have to go back in for mots

    hope this helps

    Say i did get all this done to my car, 4-2-1 manifold decat exhaust etc. How easy is it to just put the cat back in and out for MOT's?

    And if i bought the saxsport 3" road decat system would i need to buy the manifold at the same time for it all to work?

    The raceland 4-1 is a straight fit. Its more than the 4-2-1 but it costs roughly £30 to convert to the mk1 setup anyway getting all the parts from Citroen.

    Then with our race system you are looking at gains of up to 15bhp overall with your engine from customer feedback.

    I would then get hold of a VTS centre pipe and cat for MOT time from a scrappy.

    Whats the difference between the 4-1 and the 4-2-1 ? obv i understand its the way the pipes go but does each one have a different performance increase or is it just whatever people prefer ?

    From what i've heard you get better results from the 4-2-1 lower down in the rev range and the 4-1 is for higher revs.

    i think it means...

    4-2-1 = 0-60 faster

    4-1 = 60-100 faster

    correct me if im wrong?

    no you can use any exhaust system with any manifold

    what year is your saxo then i could tell you exactly what to do regards to the cat as in different year saxos they are in different places

    I dont think theres really much difference. Both offer much improvement over standard. The theory is a 4-1 will tend to favour the top end. Its more likely to affect things on a race car with many optimised parts than a road car with generally a mild state of tune.

    Well your cat is in the manifold so the only way to de-cat it would be to fit a 4-2-1 or 4-1 manifold, so for mot's you would have to fit your old manifold back on
    So exhaust wise you can fit what you want and wont have to remove it at all

    So if i buy a decat exhaust it wont actually be decat unless i buy a manifold as well? sounds like a lot of hassle to change the manifold back for the mot... is it worth it for the power you get from decat?
    basically it means that i can buy any exhaust i like improving the power of the car and not have to worry about anything?

    well if you bought an exhaust made for your car it wouldn't be labeled as a de-cat exhaust, even if it is labeled as a de-cat it would refer to the saxos with the cat in the exhaust system

    tbh i can change a manifold in a few minutes not a big job, but i know what im doing though

    id stick to an exhaust for the moment either one of these two id get
    http://www.saxsport.co.uk/
    http://www.kamracing.co.uk/index.php...vts-01-04.html

    and if you did want a manifold get the raceland 4-1 (costs about £45 more but it means you dont have to mess about moving your oil filter, which would cost about £30 to do anyway)

    Whats you opinion about the tone of the exhaust with the standard mani left on Jeff ? A few i've spoke to says it sounds a bit cack ?

    Cheers
