Please note, I installed this downpipe on a 2001 Audi A4 with a transplanted engine from a 2005 Passat TDI and a 6-speed manual quattro transmission. Fitment is very similar, however.
I wasn't sure what to expect from this downpipe, I wasn't familiar with Buzzken products. But I was very pleasantly surprised when I received it. The tubing is a good gauge and high quality, the welds look solid and reliable, and the parts used (cat, flex pipe) seem like they'll last forever. More importantly, the fit was perfect. There's very little room for this downpipe to fit in, the bends and welds need to be very accurate. I even complicated things by using a larger turbo, but the downpipe still fit just fine.
I kinda wish there was an option to go to 3" immediately after the flange, to match my existing 3" custom exhaust system. But at that point we're talking requirements probably specific to only my own application :)
