advice on cats / performance RS2

[Tzummie]

although partially mentioned in different threads, am looking for experience info on what to do with cats on an RS2: What are the effects of leaving them out? (performance-wise?, MOT-wise?, sound wise?) and what alternatives are there (metal cat? brand? performance reduction?).
Current set-up is standard downpipe + cats, cat-back BN-pipes 2x 60mm all the way, with two boxes (middle/end). Chip tuned.

thanks in advance!

If you have that system then sound wise I'd say you can bare quite a bit of noise. Removing them would get you a bit more power I suppose. If you want them in I have the BN pipes 200ci cats and they are metal and pretty good

hahaha.. "bare quite a bit of noise"..

No, I'm not happy with the sound of BN-pipes AT ALL, but will be dealing with the 2k drone by installing resonance (Helmholtz) pipes.

Am wondering what cat-less would bring in terms of power (and emission issues), or what the difference would be with 100-ceel / 200-cell metal cats.

Any noticeable improvement with your 200-cell cats, over the originals?

Speak to prj on hear, and he will tell you, in no uncertain terms what will happen If you decat an RS2 without a remap.

hmmm. I will, but sounds like a

Aren't the RS2 original cats 200cpi metal one's already?

[A80Avant]

Original ones are 400 cell if I remember correctly. I was told that using 100 cell you could still run into MOT problems. I used briefly BN pipes. I could only stand them for 2000kms. I then removed them permanently and passed them on to Billman

Well I have a pair of original RS2 cats laying around and I once counted the cells and came up with the 200 cpi numbers.

would the 100-cell metal cats offer a significant improvement in performance over the (prob. clogged) OEM ones?

thnx.
