i am pretty sure you need the O2 sensor to make it work well, there are a million topics on this tho. plus you need a cat for inspection silly

Are you sure that's the case in Ohio?

depends on the county, Dayton and Cincy I think not. We tend to celebrate the finer things in life like clubbing baby seals and burning tires whenever possible.

I was just reserching this because I too has the dreaded P0420 code & CEL light. I thought I read that while most aftermarket cats were prone to issues that some folks had luck with larger one like Miller or Eastern Automotive? There is aslo the elusive Wayne Angle Block, but I still have no idea where to find one

I just had my indi mechanic replace the pre cat (front) O2 sensor yesterday and now I have to drive and hope for no more codes before inspection day next week!

Wayne angle block simply removes the O2 sensor from the exhaust stream and this keeps the CEL off when running an aftermarket cat. Bottom line is any aftermarket cat will cause P0420, the WAB is used to "avoid" that code.

This FAQ explains the Wayne block and where to get it. Mine has worked flawlessly for the 2500 miles it has been installed.

So this will fit the ti as well? because they are talking about VWs in the link.

I could be mistaken, but I believe these are machined to be application specific. So you supply the application (your ti in this case) the unit you get is made specifcally for your application.

Thanks for the response. I just sent Wayne an email to see what he has to say. Fingers crossed.

Glad to help I'll be curious to find out what he says as I have an after market DEC Cat . So far no more CEL after replacing the front & rear O2 sensors, but I know that could chage at any point

Yeah I had replaced my OEM cat with the one Bavauto sells. It worked fine for a few months, but then the catalytic efficiency code started to be thrown again. i can reset the CEL but within 100 miles the CEL is back on. I need to get my car inspected. I'll keep you posted.

So I talked to Wayne and here is what he said.

The threads on the angle block are M18 X 1.5mm which is 99.9% of all oxygen sensors. Plus, I sell a few to the BMW crowd so I know this will fit your application. : )

Mine should arrive this Friday. I will put it on this weekend and will let you all know what the results are.
