Downpipe options - Too bad about Unitronic's disc. of the 3"

[A2Carat]

I am fairly new to the Audi scene. I've been driving my 05 B6 Avant 6spd for a year now with the 1.8t and am looking for a good downpipe from turbo to stock exhaust. I saw the Unitronic one and contacted them. Discontinued unfortunately. I have seen the common ones on the market, but none seem to compare to the Uni unit. Does anyone else sell something similar to the Uni 3"er?

FWIW, the exhaust setup is main cat (separate from downpipe), then downpipe with secondary cat. So if you want a turbo to catback aftermarket setup, you will be needing either a high-flow cat or test pipe (catless option), then a downpipe.

3" is not too common for b6 to a stock exhaust. You can see if the 034 downpipe will mate, but other than that its 2.5". I have the Techtonics Tuning downpipe. It's an ok downpipe, had it a year and the flex busted. Not sure if it was crappy quality or because I had the car sitting outside for 6 months out of the year during winter. Milltek might be better but don't have first hand experience.

Yes, from the turbo, the cat, then the downpipe, then the exhaust. Unitronics pipe was from turbo right to the stock exhaust with a smooth transition. Stellar craftsmanship it looks like from the pictures. I may just need to get it custom made. Don't want the car louder, just want some more 'efficiency'.

A HFC/TP and 3"DP, plan on the car being louder.

there's no secondary cat on the 1.8T
