i have a later engine with cat in mani, and i want to get rid off my middle silencer.

i keep hearing about decat pipes but i wont need one off these will i??

im bit unsure what i need :/

Thanks in advance

If you have the cat in the manifold you'll need a manifold without a cat?

sorry i mean i want a "race tube" but i been told i need a decat pipe and race tube, but will i need a decat pipe because it wont decat it?

25th July 2011, 18:11

no you wont need 1. you just need the sports manifold (wich will have de-cat) and just get a centre pipe to get rid of silencer

he didnt say he wants to de cat it he just wants to remove the centre silencer.

you just need a straight through race tube for a mk 2 mate.

posted just a lil late there. no you do not need a de-cat just to use the race tube. will fit straight onto your downpipe.
if you want to de-cat it you need a sports manifold (4-2-1, 4-1) mate

im confused by that? It doesnt matter if you have a race tube or not mate if you still have a manifold with a cat on its not going to decat it!All you need is a new manifold

so any centre pipe will do, i got told one runs from the decat pipe to backbox and other from mani to bacnbox?

no your set up is:manicat-downpipe-centre pipe with silencer-back box

so what your after is: manicat-downpipe-centre pipe no silencer-backbox?

if so just a racetube will do no need for anything else.
in long shot tho if you ever want to de-cat it get a 4-2-1 manifold or 4-1

25th July 2011, 18:19

there are 2 types of set up
your is manicat-downpipe-mid pipe-back box

mine is the older one manifold-downpipe-cat converter (or de-cat)-mid pipe-back box

my mid pipe also has a silencer which i want rid of lol.

so im imagining there are maybe 2 lengths of mid pipe. 1 for mine that runs to the cat and 1 for yours that runs to the downpipe???

25th July 2011, 18:23

yea i want a mani at some point, but at the moment i just was rid of the middle silencer to make it abit louder!

I think there is two lenghts of mid pipes??

Anyone tell me?

im guessing so as like i said mine goes to the cat. yours goes to downpipe.
but yeah to get rid of ya silencer just get a race tube. there is no need at all for you to de-cat it to have this on.

the one i would need:

the one you would need:

http://www.ebay.co.uk/itm/Saxo-1-1-1...#ht_2202wt_905

as you can see 2 lengths we was right haha

25th July 2011, 18:30

the MK2 set up is Manifold, then Cat and down pipe which is on piece, then either one pipe to rear silencer or 2 pipes making the centre section, i have a piper cat back sytem which consists of centre sect with silencer then the second part of the centre pipe then the piper back box.

25th July 2011, 18:31

ahhhh is the cat in the downpipe on mk2s? i always thought they where in the manifold?

25th July 2011, 18:37

mcjacko1987 just noticed where your from, we should get a meet going sometime!

who ever told you that you need a decat pipe they were talking about the early saxo's/ vts's
it all changed in early 2001 the cat went from under the car to in the manifold.
so pre 2001 (mk1, very early mk2's or vts's ) yes you need a de-cat pipe to get rid of the cat but there is no center silencer iirc.

so to get rid of the center silencer of a mk2 you'll need a 'race' tube wich runs from the downpipe/cat to the backbox. and to get rid of the cat on a mk2 you'll need a whole mani/downpipe

even so the early ones (like mine) you dont need a de-cat to have a racing tube do you? mines early phase 2 but same set up as phase 1 (cat under the car. mines de-cated, but i still have the bloody mid silencer (which i want rid of soon)

just saying that u don't need a de-cat pipe to get rid of the silencer yo need a race tube.

ahhhh right. thought you was meaning the race tube wouldnt fit a normal cat lol. i was saying it because the ends on the cat and the de-cat pipe look the same lol

25th July 2011, 19:49

Answer to your question get a racetube and it will have no silencers
