This was one of the best How To write-ups I've seen yet!
Are the valve actuator's only opening one outlet on each side, or do they open valves in all 4 outlets?

Thank you
There are only 2 valves, 2 of the pipes don't have them.

@5VBW Nick - thank you for the detailed notes. Installed the Corsa cat back on my 25 5BW today in about 2 1/2 hours. No issues, sounds great, no CEL

Recently installed the axle back Corsa Exhaust on my CT5BW, thought I'd add my 2 cents for anyone contemplating one of the corsa systems that may be reading this thread. Take it for what its worth, just trying to be helpful.
The good:
1) Installation was not terribly difficult, about as expected. If you follow the directions, you'll get the valve spring position correct and no CEL
2) Sound - quite a big difference, more presence of sound than I expected from watching videos. As others have said, you will now notice more difference between sound level settings in the various modes. If/when you want stock levels of quiet, program "my mode" to have sound at lowest level, at it will be much like stock exhaust was in its quiet settings, except perhaps the initial cold startup growl is a bit louder.
The not so good:
1) The system is heavy, the box for the axle back system was 60lbs. The tips weigh 1.5 lbs each, its like they didn't even try to keep weight down.
2) UGLY. The round tips don't look right in the the openings, and if you don't shorten the system a little bit as you go, the tips stick out too far and look cheap/silly. Making things worse, the "CORSA" printing is not removable and shows prominently - I would much prefer to not see that. And finally, the muffler sections sit a bit cockeye and hang just a bit lower than the stock setup - not a problem, but its noticable from behind the car, just looks kinda cheap. I ended up spraying mine with black super high temp paint, we'll see if it lasts.
So, to sum up, sound is pretty good I'll give it an A-, but appearance and weight are both bad, and I give it a D. They seem to have an option where you could reuse factory tips on the 4BW, but apparently not for the CT5BW. Too bad because fixing that and rotating the muffler cans to horizontal would help a great deal to make the system look less aftermarket/cheap. Just my 2 cents, YMMV.
