decat, or centre section with mid silencer for my 1.1i 98

  1. #1
    ok while ive been reading a few threads over the past days, and reading about back pressure. I know it wont make a massive effect on my my 1.1i lol, i just wondering what would be best, not really sure about the decat, purely down to the noise, but im wondering is the centre section with mid silencer is it too loud etc p.s sorry if that didnt make any sense

    1. would it be best to get a decat ?? (supersprint make) link below
    http://www.kamracing.co.uk/manufactu...e-saxo-74.html


    2. centre section with mid silencer (supersprint make) link below

    http://www.kamracing.co.uk/manufactu...-saxo-122.html

    thanks, im just getting information so i can get one in the new year

    p.s do not post if its going to say search, ive seen decat threads but only one or two for the 1.1i okay!

    Wont it be really loud though ??

    I dont think my ss backbox sounds at its full potential (due to the ye olde cat, original too), so either a decat or the mid silencer should make the exhaust better. I mean the other night my cat ting'd quite loud because it popped, i thought this isnt going to be too healthy for the cat lol, thats why im looking to replace it sometime next year.

    Nah mines not loud, i've heard a hell of a lot louder than mine and thats what i'm runnin. I bought a Sportex Racing Tube. 49 quid. Just takes out the middle section includin the silencer, perfect fit tbh. Gives it that extra rasp, mine pops bangs quite a lot now too lol.

    EDIT: Just looked at the links and the first one looks exactly like what i bought, its not a de cat btw. Its from the cat to the backbox i.e middle section.

    What backbox have you got like ?? and thats quite cheap too for that racing tube!

    When it popped the other day i thought it had shot a hole through the cat lol id rather it not do that tbh

    EDIT: ok thanks i just looked at your edited post
  6. #6
    I've got a Sportex one buddy.
    Piccy
    Cost me 89 quid, the racing tube was 49 and my decat was about 40 i think. So i've basically got a cheap ass exhaust system but i really like it.
    Quick video of sound goin through a tunnel
  7. #7
    thats not bad (price wise) upload your video


    EDIT: can anybody clue me up with the back pressure lark please ??

    my 1.1 was pretty good for sound decat straight through
    87db when tested at donnington (so not hugely loud)

    on the 2" box itll be quite nice imo
  11. #11
    would really think about performance with a 1.1 just get the de cat straight through pipe.
    Or just the straight through pipe.

    No point paying extra for the one with a silencer in on a 1.1 imo
  12. #12
    I have no silencer or cat on my magnex system is just a straight through pipe from the manifold back and i have deffinatly noticed a difference in performance it just feels more responsive.



    And its not stupidly loud and sounds pretty nice.

    De cat it !! you know you wanna !

    Steve_vts; I know there i wont get any performance gains on my 1.1i, may sound silly but sine ive put my ss backbox on its been a tad quicker to 60mph but my cat is old and im sure it blows from the front a bit, so im looking for a replacement next year

    Alex_vts; do you have any videos of your 1.1i decatted ?? if not no worries
  14. #14
    i dont unfortunatly no mate
  15. #15
    No worries lol

    Another thing is the smell, how long (a rough guess) till it wears off ?? plus police

    I was thinking that also, but it would prevent wear and tear on it wouldnt it (weathering) ?? besides keep heat down
  33. #33
    well on a mild steal system it can make it get too hot and cause it to crack by the welds
    plus itll hold water and may actually cause rusting faster

    Thats blue smoke

    surely if it was mild steel then the wrap would hold water and make it rust quicker?

    well mine popped a bit whilst driving

  65. #65
    picked up a little better but nothing hugely noticeable tbh
    sounded good and wasnt too loud (even fully stripped out)
    plus i had a bigger backboxso would add volume

    i rekon youll be quite happy with it mate
    its only on stuff like piper and ashley systems where its stupidly loud

    Just do it, they are pennies and its a seriously basic mod that works, you will notice a small difference. Dont worry so much, live a little.

    or save your money and get a decent car.

    I always take ages deciding stuff like this i just want it to be correct pipe choice that all. Its like my exhaust, i didnt want a jap backbox because the noise didnt appeal to me, than after asking about the ss backbox and seen people reviews i thought yep, il have that (Great choice by me) just the centre section to sort out.

    What about M.O.T time, will they still mot it, with a decat ?? or will they say "Hmm you need a cat, £200" if you get me lol, its not till after the next summer i dont think, so it should of worn in buy than i suppose.

    Whatever floats your boat tbh, but remember drivers with loud exhausts and saxos just make people think 'prick', regardless of the model. but especially 1.1's.

    Its just factual, im one of those drivers
  82. #82
    round the lanes was where it spent most of its time
    hence i killed the brakes a few times fading them out (i drive rather hard)

    was prolly my favorite car to drive handeling wise out of the cars ive owned

    My ss backbox isnt that loud to start with, so i doubt a decat will make it a headache.
  84. #84
    decat will add a bit of noise

    but the 1.1 has no other boxes so it wont get much louder

    My cat a month back started to rattle, so i took it off and these little balls came out lol, so it shouldnt be long and inside should be completly rotted, they should shoot out of the backbox (in theory) obviously the ss backbox is clean through so whola

    full race system strait frew you only have to put your cat on once a year! decat john do it!
