Everything Antarius had to say is pretty spot on. There are no valves on the exhaust and I think it shows significant gain over a stock A3 that is essentially silent.

Based on my experiences with exhausts I would call the Magnaflow exhaust fr the A3 more of a sport touring exhaust type because it is a pretty comfortable tone, but aggressive when you want it to be. In Drive mode, there isn't a huge difference in resonance.. but once in Sport mode (80% of my driving) the exhaust starts to come alive quite a bit more. The acceleration in the video above provides a good example of what I mean. It's still a 2.0 liter engine so don't expect anything incredible, but I've loved the upgrade.

I installed the exhaust system myself and I kept the stock components just in case I ever need to change it back. It's a very straightforward install as long as you have the right equipment/access to comfortably and safely get underneath the car. Would recommend this exhaust if you're wanting more out of the A3.

Mark I'm not sure why you're so critical of Magnaflow, I think this exhaust has above average quality and performance for the cost. I don't regret the purchase at all. I've had it for almost a year in Seattle/Spokane weather and the stainless steel tips and tubes show no signs of wear or damage.

There are valves, but just near the turbo. You can turn them on/off and hear them clicking via vcd, but its not the valves that are on the S3 muffler. And correct, nothing after the cat.

Its interesting because when you setup the exhaust valves to open via VCD, its the same valve control signal to control the S3 muffler flaps. So when the S3 has their muffler valves open, another valve closer to the turbo opens as well.

Does anybody make a catback specifically for the convertible?

As far as your question, no, I don't anticipate anyone will make a cabriolet only exhaust. The cab is probably 10% of the cars sold, and the Audi aftermarket is already smaller than say, VW or Subaru. Then you have to consider that many people have leases, and aren't going to modify their car at all. But for anyone that does buy their car, cutting 1 - 1.5 inches off the stock downpipe to permanently be able to fit any and all aftermarket exhausts is not a problem. It's literally a 2 minute fix for any competent exhaust specialty shop, of which there are a few in every city. Like I said, they only charged me 50 dollars or so for the entire install.

Being the stubborn guy that I am, I strongly considered putting on the exhaust and trimming the downpipe. I would keep the old exhaust, reinstall and buy an OEM downpipe when the lease was up. However, it looks like the downpipe costs about $1100 plus installation! I'm not that stubborn.

Would it be possible to trim the exhaust system to fit the stock downpipe?

here is what im opposed to:
having extra exhausts hanging around my garage.
replacing something moderatly expensive that works perfectly good
a 2000$ exhaust would be like 7% of the price of a brand new a3.
it will sound mad annoying
the gains are nominal
fitment is a risk-
expensive labor bills
warranty issues
many hassles
=TOTAL FAIL

spend that money on a chip

Wow that CTS Blow off valve is A LOT louder than I anticipated. Seems louder than the actual exhaust. Wanted one, but not sure I'd want that much attention.
