for seat leon 1.8t ko3s

or milltek decat?

98x sold vs 8x sold, nuff said Milltek should be 2.5" as well. Least resistance behind turbo is best, so 3" decat. Get the Toyosports, nice bit of kit (have it myself)

Also get a lamda angled spacer

Where abouts in Kent are you? I know of a Toyosport's decat/downpipe and angled sensor (and 2nd lamda if needed...) going for a good price

That's the same downpipe just different sellers

what angle spacer can i use? its an 1.8t seat leon cupra auq

 

[LEE69]

Use any of ebay angled one is better, but chances are the eml will still light up.

Ive been driving with an angled spacer (eBay) since the beginning of november and havent had a EML since

 

[LEE69]

No idea why it does and sometimes doesn't Mr OCD iirc doesn't have a spacer and his doesn't light either.

Why do you need a spacer?

 

[LEE69]

It keeps the 2nd lamba sensor out of the flow of the gas, and having no cat it is a different gas now,compared to a car with a cat.

 

[nd-photo.nl]

The higher velocity of the exhaust gases is a result of decat, the second lambda expects lower speed and cleaner gases

 

[jlhiggins]

Are the straight lambda spacers no good then?

 

[RICKY3]

Are the straight lambda spacers no good then?

You need the angled one due to space being limited

Make sure when you fit anything to do with exhaust or lambda sensors that you copper grease everything that has a thread and ideally use stainless steel nylocks, bolts and washers makes everything so much easier should it need to come off again.
I had this on my car:

Custom made so I could take out the de-cat and fit in my standard cat. It's also for sale
