    Can you get good cheap sports exhausts? How much do they cost?

    what are you looking for
    back box
    cat back
    or full system ?

    they obviously get dearer the higher up you go, decent back box might cost you around £100, cat back around £300 full system id say around £650 using a sports cat and a little bit cheaper using a decat.
    note that you will need to swap the cat back on for the mot unless the cars running spot on for emmissions even then you might struggle

    make noise.

    thats about it. a cat back system on a 1.4 might give you around 3 or 4 hp and a full system maybe 10 at most

    theres also the throttle responce to look at, again on the smaller engine your not going to feel much difference

    Would there be much difference in throttle? Would the car use more petrol if I installed a backbox on its own?

    there was on my 2ltr prelude felt much sharper and that was with everything part from the exhaust manifold changed.
    car shouldnt use any more petrol really however you might find your self reving it more to here the exhaust so that of coure will use more

    it is really, i just dont see the point, on a 1.4 anyway

    bigger cars do gain a bit from full systems, the only reason is the engine is so big, and its restricted because of a piece shooter exhaust

    turbos do benifit alot from full exhaust systems, did you ever notice a huge exhaust on a turbo, and its not that loud?? i dont know excatly why this is, but i presume its part of the turbo re-spooling the gases??

    but on a 1.4 mate, a back box will do you, it will sound nice the way you want it to, and you wont spend 100s on getting about 4 bhp

    thats my opinion on it anyway chris:D

    Big bore exhausts are usually fitted as part of a comprehensive tuning package. None of the mods alone will do very much. But a bigger pipe and different rear section will look nice. It'll sound nice as well, if you like that sort of thing. Not for me, personally, but that doesn't mean you shouldn't do it.

    Ok thanks boys. Do you know any good places to get a good backbox? Please no one say Halfrauds lol. And can you get exhausts where you can adjust the volume.. I don't want it being too quiet but I don't want it being as loud as an F430.

    No such thing as an adjustable one I'm afraid. The exhaust is there of necessity (ie. to get spent gas from the engine out into the atmosphere).

    The set of compromises is always flow against noise.

    your right, thats the things with mods, youll get 5 tops from each mod you do, but when their all together, its like it helps each thing out

    i put it this way, an induction kit = 5 - 10
    an exhaust 5
    induction kit takes in more air, if you have a standard exhaust, it takes in more air than it gets rid of, you could lose bhp
    but 2 of them together will bring bhp up, and make the car more responsive

    its the same case buying iridium sparkplugs, useless unless you have ht leads

    Will different backboxes have different volumes? I've noticed some cars have really loud ones some have reasonably calm ones. How do I know which are which when I look in a store?

    You can get a full system tuned to your preference

    And there are actually some 'tuneable' backboxes!

    Made by either savage or Rage, I will find out for you ;)

    Cool. I'll look in a few shops. Trying to get something like 2 tuneable 2 inch diameter tailpipes

    Rage I think went out of business, but their universal backboxes are still available online. They did bright anodised blue and red ones so if you have a bright blue or red car, it'd look the nuts. That's what I think, anyway.

    I had a Peco on my 205, it sounded mint, not too loud but did make a pleasant difference to the sound, like it made her purr like a sleepy tiger rather than wheeze like an 11 year old 1 litre, AND I could then get up hills in 4th, instead of having to change down into third (she only had 4 gears, bless her!!! :) happy dayz)

    the "tunable" ones normally had an insert you could put in if you were after a more silent exhaust. rather than having a 5 or 6" pipe the insert knocked it down to a 2" one while still looking like a 6".

    some of the bigger cars, aston martin and corvette use this method, have a butterfly valve in the main pipe with is controlled along with the throttle, in other words when you put the foot down it opens up fully to give the deep noise and while cruising its slightly closed to keep the soundsdown

    Is this not also done to encourage cylinder scavenging when the engine is not operating at it's optimum resonace point?

    hey chris
    Could try local powerflow exhaust centre, had these on my last 2 cars,£200 to £300 for cat back system & lifetime guarantee as long as you keep the car.

    £200 is a bit high. I checked Halfords and they had a backbox for my car but it was £280 and upwards! They do universal ones for as low as £70 though. Are universal ones really that bad? I can't find anywhere where I can get a good, but quite cheap backbox.
    I can't try powerflow because they change the whole system. My insurance company won't let me modify my car unless I pay an extra few hundred.

    Have you asked powerflow? im sure they might be wiling to make you a back box alone.

    your insurance company will need to know even if the backbox is changed - they will use any reason to get out of paying

    depends on your insurance company, some may allow it.
    i know when i went to put on the civic it was going to be an extra £90 a year. like i say some will use any reason to get out of a payout so would also recommend that you tell them about gearknobs, pedals etc most wont bother with those things but its better to tell them
