Exhaust comparison (DSG vs. Tiptronic)

[Adub-Drew]

Well for a while now I've noticed that many of the new dual clutch equipped car's make a "fart" sound if you will, whenever they shift gears. And i guess i kinda like the sound because it's better than having a lame auto exhaust note. But from what I understand only DSG (dual clutch) car's make that sound. However now Im seeing video's of the b8 a4 6at (tiptronic) making that same sound....

Is it that all tiptronic's make that sound, but just that you need the right exhaust to get the noise? If anyone know's too how that sound is produced, I'd love to know...

I found some vid's too...

Its the Ecu retarding timing to shift i think. I hear it with mine a little bit not as pronounced as that.

dont quote me but im pretty sure its a drop of fuel that gets burned in the exhaust when it shifts. At least thats what Clarkson said, lol

Clarkson said that about the RS5, not the A4...

Never noticed a sound on mine during shifts - ever.

DSGs are technically manual transmissions. They have a tendency to sound more like manuals. Some models even rev match on downshifts.

Yea i heard that on clarkson's review and yes it was the rs5... It was just something i was curious about, and wondere'd if my tip would make those noises.... I guess even if it does its going to be very faint..

only newer vw/audis do. b7s do not.
