Is it possible to remove the cat on the standard exhaust even if its not legal? ANy and all ideas well appreciated. After being at top gear this year i heard so many exhaust just pop and bang when they were being revved specially when the cars were just crawlling along in first gear. Thanks James | ||

I was just wondering because the jCW cars seem to backfire alot and i was hoping i might just be able to take one or both of the cats from the exhaust or something. Also just wondering how cars do make the noise/effect. | ||

As Dave said it will be unburnt fuel hitting the pipe. For some strange reason my MINI has always been really good at this. | ||

Yeah it was added noticably to the facelift MCS or if you remaps a pre facelift with MTH as I found. Yours is probably just overly rich like mine is..... MINI Project Loon : MINIProject.co.uk | ||

But i guess there is no easy way to make it backfire pritty much everytime i drive fast and let of the throttle. I was hoping that if i took out a cat or changed something small i could get a sweeet sound. I guess i will have to get a new exhuast. Anyone recommend a good exhaust that will sound sudate under normal driving but loud popping and banging when hitting it hard. Thanks | ||

You will as dave said get a better sound/note without the pre cats. | ||
