    Hi all. I have been thinking about this for a while and not sure of what to do. I have read many threads saying that removing the cats ups the performance slightly because of less restrictions in the exhaust which makes sense.

    BUT others have said it makes no difference and makes the exhaust noisy. Im running a standard exhaust as I dont want too much noise, I have heard cars with the cats removed that make a nice raspy sound which I do like.

    I have found a place that will do the job for me, and there work is top quality..http://www.topgearaylesbury.co.uk/co...page/Itemid,1/

    Just wanted some opinions before I book the car in....

    Cheers....

    Emissions are not a problem on mine as its Pre-cat test....

    I like the look of the standard exhaust, every aftermarket exhaust I have had always sounds too loud, and the genuine exhaust flow very well anyway. They recon is will cost approx £80-£100 for the welding work. I cant justify over £300 for a new exhaust system though..

    for £80-100 is well worth getting it done then steve, i do know what you mean in regards to noise mate, i think the standard system is just about right too, a nice bark around 3000rpm

    Thats it Ralph. I had a Scorpion system on the car before. It was well made and looked good, but everywhere I went people just looked at me. It did my head in on the motorway as well.
    I prefer the sound of the induction kit over a loud exhaust...

    go for it! I had cats removed on my 2.8 Audi and sounds much better with stock back box, revs better as well. Later I added custom made back box (quiet one), overall it was a quiet and nice sound when I was driving round the town or motorway and sounds amazing when you put your foot to the floor,
