Hey Vin,
I have the Staintunes. They are well made, up to their usual standard, are easy to fit, sound great, with or without the baffles, and even without the baffles are not
too loud.
They tuck in well, are longer than stock but extend in both directions.
Staintune claim that they don't require remapping, and I found that to be the case, however my dealer convinced me to try the off road map. It still runs OK, but feels a little richer, maybe not quite as crisp as before, but just as smooth, and even all through the range.
Last weekend on a 500 km ride I found that my economy has improved with the (richer) off road map - 16km per litre as opposed to 15km per litre with the stock map.
I intend to put it on the dyno soon with both maps to check the air/fuel ratios and power and torque. The bike feels good to ride with both maps, so I can't tell you any more until after I dyno it. When I have the stock map in it I might put the stock pipes back on to compare the power and torque of the Staintunes to the stockers. It only takes about 45 minutes to do the swap.
The guys at Staintune told me that they keep pipes in a warehouse in the US and you order online from their Australian site, and then they ship to you from their US warehouse. Last time I checked they did not have the 05 S3 pipes listed as being available in the US but if you email them they respond very quickly, so they will tell you if they have them.
I have no connection with Staintune, I just like the pipes.
