Figured I'd update this:
The clutch is broken in - this is the best clutch that I have ever owned - previously I have owned an ACT clutch on a supercharged K20 Acura; and a clutchmasters clutch on a N/A b16 Civic. I love the SB - the pedal feel is perfect, engagement point is perfect, it holds the power down very well. I love it, favorite modification that I have done to the car.
Unitronic downpipe: love it. It was more expensive than some of the alternatives but it is a quality piece. Previous downpipe experience comes from an HPA unit on a Mk6R. They are similar, with the welds on the Uni being better. At the time, the HPA also had a 100 cell cat from memory, this one has a 200 cel. I do not notice fumes, at all. The car has become a lot louder between 2.5 - 3.5K RPM, but I like it. I've always preferred more noise than less. I do not think I will be altering the rest of the exhaust system though (famous last words).
Uni stage 2 tune: They provided me with two options after I called them - I am not keen on looking for 93 octane gas whenever I need to fill up, so I asked them about a 91 file and they provided me with three choices of stage 2 files: 93, 93 with pops and bangs and the 91 tune. I'm not into pops and bangs so I did not mind not having this option for the tune. I like the tune, it has improved drivability, the car spools faster (i understand this is the dp), there feels to be a significant amount of more accessible torque down low. It is a very linear tune, the car drives like stock, but with more power. I'm a fan. I was bashing the stage 1 tune, but feel completely opposite about their stage 2 file. I don't think I will be changing it.
The rice boy in me wanted more swooshing noises, so i picked up an IE intake. I plan to grab a uni intercooler in the summer and I think that will be that for "power mods". After that I think I'll grab a set of wheels with some nice tires and eventually replace the struts with some b6's and call it a day.
In the end, I do not have regrets about spending the money, it was worth it, the car is that much better now.
