-How did you clean up the inside of the headers? I noticed the inside of the primaries on mine were pretty dirty with gunk and metal shavings.

Honestly they still look about as good as they did when I put them in.
Just make sure that when your ready to put them up and in to USE SOME GLOVES and keep them nice and shiny. I obviously failed to do that.
I did only some basic polishing on them. Just enough to get them to the point you saw in the pics. That was maybe 2 good passes with some Never-Dull and some simple buffing. They were as shiny as I really wanted them. And since 75% of them would be tucked away in the engine compartment, I really didn't focus too hard on it. The "shine" they had may have faded a bit, but no odd discoloration so far. If you do at least what I did, you'll be happy. Any more and I think you'll be that much better off.
Ahhh, the pipe cleaning.
I was going to include that in the writeup but I didn't know if anyone actually did that.
I would have thought the more mechanically inclined types would have access to an air hoze or something to blow it out.
Alas I did not, so heres what I did.
I took some thicker gauge speaker wire and made two lenghths, maybe about 3' a piece.
I tied each length to an old sock and made sure there was enough sock tied to not rip when i pulled on either end. So... it looked like this
loop---------- wire ----------sock---------- wire---------- loop
From there, I pushed the loop end of one wire through the flanges and out the collector, the other end with a loop was hanging out the flange end.
Once I could get ahold of the loop inside the collector, I just pulled the sock through. I did that several times with each primary tube.
And most times pulled back and forth while the sock was in the primary to sort of scrub the inside a bit.
Be careful here, there's a reason I tied it on both ends, you do NOT want to get that sock stuck in the middle of your primary. I imagine you would have a hard time getting it out if the wire ripped out of the sock or whatever, hence the tie on both ends.
Then for the collectors, I just used various longer type accesories to get the gunk out of there and called er done.
Again, this was part of the process of making the install my own.
Did i have to do this, maybe not. I certainly never heard of anyone else doing it. But I'm a simple man, and have simple logic. Dirt and gunk bad, clean out.
Done and done. Does that make sense?

IMHO, that was a GREAT write-up. It was very informative, and to me, it seemed you eliminated a lot of unnecessary clutter, like the EGR delete and what not. I had a similar experience with my QTP install. Unlike you, however, I did not think I had to get the car up as high, as you had, and eventually I did, but, that driver' s side went right in after it was 100% verticle. Passenger' s side was a breeze, OMG. With MACs, I had to pull the starter out and crap. What a pain. Like yourself, I chose to clean the insides of the tubes. I too polished them, for a few hours, in fact. I can report, after close to about 1500 miles, they are a little shiny, but discolored. They have turned into a orangeish-brown finish, but not sorts of rust or corrosion. I like how they look now, in fact. I think it was worth my time
I had elected to keep my Borla, so I had QTPs' s cat' d y-pipe, and that was " fun ", but, your write-up on the duals was equally as good. This sounds like a quality kit, and I, like yourself, don' t think the cleanup was that big a deal. There were some areas on my Borla that needed a little TLC, so it sounds like you purchased a quality product.
Again, a great write-up. Welcome to the LS1

If it matters, I have had some dyno numbers for you to consider. One can not make a direct comparison, but, maybe a reference.
I had my car tuned, for my QTPs early November. With my stall locked, and a QTP cat' d y-pipe, my car put down 354RWHP and 360RWTQ. For reference, unlocked, it put down 317/307.
Now, last winter, under similar conditions, with the only changes being MACs, with cat' s and the OEM converter, it put down 334/355, with just a Diablosport tune.
Another 20RWHP, with a tune, is not bad, over what I had with some MACs. Adimittedly, like I said, the MAC tune was just a custom internet tune, not an acutal dyno tune, like with my QTPs. Hopefully, this is helpful.

Sadly, I didn't dyno the car when it was stock, and since I have all the mods in my sig.
Also unfortunately it is now winter up north here so the car is a garage queen for at least 5 months or so.
I am going to try to learn to tune during this time and maybe will go get a dyno after I am satisfied I have tuned it sucessfully.

Great write up. May I add when you asked about the clamps and tightening: typically people do use breaker bars, but you usually have to go back over them 3-4 times after heat cycling to make sure you get a good fit. After 4, it's done.

When you get done, just stuff the carpet back under the side panels, replace the sail panels and shut the hatch.
You could do it in 2 minutes if you're violent enough.
PS - Adding this to the exhaust sticky!
