Decat Pipes



  • Would love to de-cat mine.



  • I have to have the 3 back off the road by end of next week, so once I've swapped the cars over, I can then get to work taking the exhaust off!

    Fingers crossed, I should have more info for you by end of month! :)

    Sorry for the wait guys!



  • I had a decat on my 1.8 and it didn't make any speed gains, the MX-3 seems to have a good flowing CAT anyway. But it did make it sound a bit beefier but I had a powerflow cat back not standard.

    I also ran a CAT that had the innards knocked and it made no speed gains either, I was on stock exhaust then which sounds crap anyway so it didn't really make it sound any good either.

    I fitted the MX-6 headers, now they made a big difference to the sound and the response. But I did have to put sound deadening in the boot, and in the end I'm having to change my backbox as now its annoyingly loud.

    Here is a pic of the DECAT I use with the MX-6 Headers/downpipe:

    Notice that its offset not straight!



  • any word on these yet?



  • I have a stainless pipe that exactly matches the cat. I also have the stainless headers, and in my case they shortened the oem midpipe. So its stainless headers, stainless pipe, shortened oem midpipe, stainless remus backbox. I can still get those replacement cat pipes, think they'll be about 80 gbp, with perfect fitting flanges and high quality (lot better than the headers) stainless pipe.



  • Its for the 1.6 that i need the decat.



  • to get a quality decat pipe, I bought 1 from america, it cost about £35 inc P&P but they dont come with the offset but I have paid another £15 to have it cut and rewelded at the correct angle. So its cost £50 I get mine back this week so can fit it soon.
    I also found that the american ones are built to look like a cat is fitted inside a large stainless box.



  • djmp you got a link for that? or would it be possible to order it through you inc the extra work? bit cheeky i know but would love to get that bit fitted and out of the way! :D

    This is the one I bought, it is slightly oversize and the small end is not angled even though it states it fits directly onto an MX3 but its a small job to get it done at a welders, I could have had one made for the same money but the amount of metal and workmanship that has gone into this one would cost you nearly £100 here so I thought it was good value.

    I have one, its not, its about 20mm too long and the end is straight and it doesnt fit 1.6 because the center pipe and cat are all one part
