    You could try and find a second hand cat section and chop it up Simon. The exhaust is not hard to change on an E36. You could have the decat section, the the ncat section for MOT time...

    All E36's came with cats as standard in the UK...

    Is the single pipe a lot more restrictive than the twin pipe then?

    Yes Lloyd. The 323 exhausts join into 1 and this restricts the flow. The 325 and 328 runs twin all the way through the backbox and has twin cats. Flows much better....

    Huh, learn new stuff everyday. Would it have worked in the same way on a 318is then with two pipes instead of one ? By joining a 325i exahust sytem where the 318is joins for the sensor

    If you are good with the welder its possible mate. The 318is flows well because of the tubular manifold. May give you a couple of extra ponies though..

    M3 rear box would look better on your car mate...

    Yeah, it would do. The powerflow ive got on at the minute isnt bad, just abit noisy. I was under the car the other day and the actual width of the pipe was ridcilous. It was 4.5" wide from cat back , i thought you only needed it that wide if you have over 400bhp or something??

    Anway, i should save an exhaust system really for when i go to a 2.5/2.8
