Sports Cat

[cho]

Does anyone know if a high flow cat for the sxe10 would fit on an is200?

[Dave-Ellen]

no

[sparkystav]

Get a custom decat made up. mine only cost £100 and the cats been modified so the pipe can just drop out and cat back in at MOT time.

thanks for the help guys

Just this place mate: http://www.westgatetyres.co.uk/index.asp

Local Powerflow exhaust maker.

Just told them what i wanted, we got it on the ramp, i agreed with them what they needed to do and left it with them for a few hours. job done.

I've got a picture somewhere i'll find it now.

Here you go:

Just to the left is where the manifolds two banks join to one then the cuts been made.

The cat has also been modified so it has a fanned end on, so i undo the flange and exhaust clamp. Refit the cat and send her off for MOT.

Bud I do hope you dont ever get a roaside emmissions test :o

(seen a few in London recently, pulling cars at random)

[sparkystav]

They do they do chance you take i suppose.

Anyway, way i drive itll be warmed up nicely and might pass lol.

[DJ Wozza]

erm yeah course :winky:

Looks a nice job mate, I'm only messing :D

[Anees]

You got me worried now Wozza with these roadside emissions tests. Do they fine you if you fail or is it worse? :o

[aaronabbott]

worse mate just make sure you dont drop the soap :winky:

[DJ Wozza]

it's pretty bad, no vehicle defect rectification notice, just a plain old prohibition notice instead so I'm told :o

[Yeldarb]

Woulden't the 2 pre cats alone be OK?

If the emissions are within tolerance surely the MOT won't be a problem either. So can we remove the main cat and leave the others alone and stay within the law?

[Yeldarb]

Had a chat to my MOT place and they answered all my questions.

A car does not have to have a CAT to pass the MOT, they can't fail it if it is not there (not my words but the MOT place). BUT the car will not be able to reach the emmissions level required if it does not have one.

So you can remove either the 2 manifold ones and leave the main one in or remove the main one and hope the 2 manifold ones are up to the job.

Or remove the manifold ones and put a sports cat in, which is the route I will go with mine.

[sparkystav]

The problem with leaving the precats in is that there have been instances of them melting and blocking up the exhaust completly.

How much is the sports cat may i ask?

Powerflow want £200 fitted for a 200 cell sports cat. So cheaper than the prolex one at over (just!) £300 unfitted.

mine goes in next Tuesday, I will be looking for a std. manifold to strip the cats from and add clear pipes. Then all modding done till next year.

[sparkystav]

And a plain decat pipe (also from powerflow) including standard Cat moded to bolt back in was £100.

Suppose it saves the hassle though

If I keep my car next year I'll be doing this an asking Powerflow, i want it so I can put it all back to stock afterwards.. got them to do a smiliar thing from the cat to the back box :)

So Stav is your system just straight through all the way now, did powerflow go from the manifold to the cat? Then take out the cat etc?

Hi, if you take out the 2 pre-cats what do you do with the lamda probes that are in front and behind the pre-cats? I'm thinking of taking off my pre-cats and want to know whats involved. I have a IS300 by the way! :)
