I have a 1.6 TS CF3 156. It has been working nicely after the main cat got destroyed 60k kms ago (the cat became see-through). I am now looking to remove the entire cat system and I am wondering about the lamda functionality, will the ecu adapt without giving the notorious engine light? I have...

Hi everyone. After years of delays we are now considering building a pair of decat exhaust manifolds for the Brera/Spider and 159 3.2 V6. Is there anyone on here who would still be interested? We had lots of interest in these in 2016 & 2017 but not so much recently, so I thought I would ask...

I need info and advice about deleting cat on GT jtd. Short about car: there is 2 cats,one is on turbo charge,and car dont have lambda sensors. What I have on mind,is to buy 2 original cats to remove that ceramic stuff inside it,and to install on car that empty cats. Is this ok, or I should just...

Hi guys, I have an Alfa Romeo Mito 2011. It's the TCT transmission and 135bhp model. I'm looking to get a decat or a sports Cat fitted to my car so I called up couple exhaust shops near me and they've advised that it's almost Impossible to do as the Catalytic converter is on the manifold...

Hi at the moment I have a 2.4 jtd 156 sw, de catt, remap, full flow air filter blocked off egr, and straight through rear box, unfortunately at 150,000 mls it just scraped through the mot on emissions. I am thinking of buying a 159 2.4 jtdm sw, and would like to know if you can replace the catt...

There are already few threads about removing pre-cats from Busso, but most of them are old and about 147/156, not GT (not sure about differences there), so starting new one. I find the pre-cats really ugly, heavy, restrictive and overall unnecessary, so I would love to get rid of them. I have...

Hi, i have a 2001 Alfa 147 Selespeed, i wanted to get rid of the pre-cats but also the first two lambda sensors and get a setup like the cf2 Twin sparks had. What do i have to do to achieve this? Regards

Hello guys, just wandering if anyone has any de-cat downpipe for sale, currently have a quad exit cat back on my mito Q.V. but looking to de-cat for a bit more noise and flow, thanks

Just to let you know, we've got a couple of pairs of our stainless manifolds back in stock now. Give me a ring if you're interested 01768 879171

Anyone know where I can get a decent one.. There's on on fleabay but I'd prefer somthing that would last.? Autolusso want 150 and I can't Warrant that. 8v 147 1.9

This is a very high quality product, beautiful welding. Brand: Wizard Exhaust, a real piece of art. As good as new, half year old. Stainless steel, straight through design. Increase of power clearly noticeable, but without the annoying drone / raspy sound you would get with a unsilenced decat...

Guys I have a 2016 Giulietta Veloce 1750 (QV) and have bought a decat downpipe. I know i need to map the car to fit but, will i be able to fit it myself then map at a later date??? I don't mind the EML and being forced into N mode on the DNA. But i don't want to be put into Limp Mode. I can fit...

Hi all I'm thinking of replacing the mid silencer/ cat with a de-cat pipe. Can any say if this a good idea or bad, what are the downside to doing this? 2006 1.9 JTDm thanks

The car has been down on power lately, and power consumption rose. I figure the cat could be clogged because the car ran for some time with a snapped turbo hose. Either way, I wish to do this. Is it a pain in the ass to take the pre-cat off and put a straight pipe instead?

I'm thinking about replacing the cat from the turbo/downpipe, have any of you who have done this had any problems with the car or at MOT time?

Hi all, Guess starting a new thread will be better for anyone looking into this in the future. As Vauxhall is much more common, toyo sport do a decat pipe link below, will this fit? I know they share the same engine / turbo...
