External wastegate vent to atmosphere

[Corey]

Any thoughts, good or bad.

I am considering doing this to the ur and potentially to the S4 also.

DO IT!!! I love the noise, this is being done to mine before GTi this year. MarkH has it done on his car but finds it too loud(he's old tho)

Thanks Tom for the 'MaxP' response... Blummin kids these days... heheeh

The separate plumbing for the WG output (like on Mark's monstah) has indeed a very distinctive noise when it starts to open. On the occasional twilight flypast my house I totally love the sound - its reminiscent of the Group B quattros of old - totally spine-tingling noise. However I'm not sure that living with it day in day out would be as enjoyable. On full fang it sounds lovely, but in mid range its a bit farty and draws attention.

I don't think there is any quantifiable advantage - except a less expensive design for the main downpipe as it can ignore the WG collector pipe - and you can dispense with the corrugated section for thermal absorption.

A good compromise might be the separate WG pipe having a little silencer. But you have to hear noise on full fang to make the right decision for you !
