Hi fellows

Previously, you guys have answered me a lot of answer regarding the ECU and thanks for that. You guys are great. My car is in the workshop now and waiting for the parts arrive.

During this period, I had chatted with my mechanic, he mentioned my factory exhaust manifold should need to polish cos I am upgrading my ECU. This will make the air flow run better but it is not cheap. Around 200. But I have found the polished exhaust manifold in ebay and the price is around 200 as well. is it worth it? any brand you guys can suggest?

Should I polished the factory one or buy the new one from ebay? I remember there is some difference shape or design exhaust manifold from 1997-2002 audi a4 b5 1.8 turbo but I can’t remember what it was.

Here is the link.

I am not sure would this fit on 97 1.8 turbo AEB engine? Please help……

STAY AWAY from the ebay one. Since you are only chipped, getting an exhaust manifold won't do too much for you. You will be perfectly fine without it. Later on when you upgrade the turbo then you should consider an aftermarket manifold. But if you really want to buy one then get one either from 034 or ATP.

dont even touch your manifold.. You are only chipped, there is absolutely no need. www.atpturbo.com www.034efi.com

if you were putting on a k04 id say to gasket match it, otherwise dont bother.
