CAT Install and DIY
Can anyone offer advice as to whether installing a new catalytic converter on a 99 A4 Quattro is a job that can be done by someone with average mechanical ability? Also is there a preferred converter? My mechanic is saying that there are no aftermarket CATs that seem to bolt up cleanly and that going with OEM is best (which I find hard to believe?????

That's a load of crap. There are after market cat's out there. Just look around. I bought a high flo cat for mine and installed it in my garage.
To install the new cat you have to remove the air box to gain access to the cat/turbo bolts and remove the O2 sensors. You unbolt the cat from the downpipe, and remove the cat and put in the new one. It;s not hard work it just is a PIA.

Yep there are plent out there.
You can even use a universal, measure yours and get one close to your size. Cut off your old flanges and have them welded onto your old one.
If you have a 1.8T, i'm positive they make direct AFTERMARKET replacements.

Here's what you need man. Labree makes good stuff from what I've heard and they are quite a bit cheaper than any other aftermarket HFC I've seen. Definetly don't go back with OEM. If you've got to spend money you might as wel get more power. I'll be getting one myself within the next few months.

techtonics tuning also makes a highflow cat.... you could also go for a test pipe if you dont have to worry about emissions, would give you a little big more powert/torque, considerably faster spool time and be about 1/2 the price.

I had every intentions of getting a test pipe but reconsidered for several reasons. First, if Alabama ever went to emissions testing I'd have to put the cat back on. Second, there's no way around it, you're gonna get a CEL (there are ways to clear though). Last, I've heard that with a test pipe and a cat-back exhaust our cars are annoyingly loud. If you rev it up in neutral enough to hit boost, the exhaust will pop. Plus, the dB are too loud for comfortable highway driving. I'm not incredibly bothered by noise, but I have an Audi. They aren't suppose to be loud IMO. I'm sure the HFC is more restrictive than a test pipe but it should still help quite a bit especially if you ever go with a K04 or a Garret.
