Is there exhaust flow out the tail pipe? Are there current fault codes? More input>
OK I have a 2000 1.8 with a Apr chip intake dv and cat back. I was driving home somewhat hard and started to smell something and was peaking at 10 so I popped the Hood and the Turbo was glowing red. So today it wont go over 10 psi and sluggish. What I'm wondering could it be the cat or Turbo? Appreciate any help thanks
did it smell like rotten eggs? im not too familiar with the a4 since i just bought one but have years and years experience with dsm's sounds like you melted part of the cat(the inside) causing too much back pressure off the turbo causing it too glow red. You will have oil being burnt up a little since the bearings are getting over heated from the turbo itself. Since you have a secondary o2 delete you wont throw any codes unless you get too much backfire and it causes a misfire in one of your cylinders.
I have APR stg 1 on my car with intake and DV and just put in a test pipe with the stock exhaust. I can see the difference in how fast the k03 spools up now ! 2.5 " coming, but that stock cat holds so much back on the turbo. good luck look into a HFC or TP worth the money
other then price, you can get it off ebay for 100 ish bucks that works or one from 034 motor or atp for like 150 ish all bolt on come with hardware
I just got this one (ebay) ^^ the fit is not bad. it all bolts up to what the stock cat was. some other people have used it too

use a non fowler spark plug spacer. they are in the help section at the parts house. I think the drill bit size I used was a 7/32 or 17/32 which ever is the biggest of the 2. then you will need to sand or file the lower inner dia. for exact fitment.
Any VWs made after 92 are usually only good for drive train donors.
so this or what RAI has should work. no CEL yet if this comes up sorry for the noob ish but it will not hurt my car right running it like that ??
