Decat Pipes
-
what would you need as a template? don't suppose a pic would do it? i asume that it would not be mot freindly? want one though if it can be done.
-
MOT wise it does not matter an emission test will be carried out according to the engine age. Most cars that have de-CAT pipes fitted pass CAT emissions test, just make sure the car is very warm before the test is carried out.
-
You can also put in additives that lower your emissions for a day! ^^

Ok, so to sum up, these are the numbers thus far:

-Ash
-DJMarcoPolo (straight through middle section)
-MattuhhWill hopefully be getting a rough quote this week, so let me know if anyone else is interested so it makes it worth his while!

**For reference, here's the MX-3 stock downpipe next to the stainless KL version:
The branches are longer on the MX-3 version simply because the manifolds are shorter. When mated to the correct fanimolds, this section is the same length. You'll note that the cat-side section is markedly longer, however…
From this image it looks like approximately 190mm longer - so you'll either need a 190mm shorter cat, or a 190mm longer mid/back section if you're going decat. I can measure more precisely later when it's not windier than God's arse outside.**

any news on them decats yet??
-
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.
-
yep thats sweet, it does say its compatible though to the mx3,

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
