I'm contemplating getting either of these for my '07. Would one be better than the other. The MSDS are a bit less expensive, but are they any better? Lastly, (with price being a factor) would I be able to use the remainder of my stock exhaust setup (from the cat back). My biggest concern is the pre-cat failure(s). I will have to have this installed, as I have niether the time nor place to do this myself. So my thought was to get the headers first, then when the funds are available get the Magnaflow.
Questions regarding Headers: Nautilus or MSDS for an '07

According to the MSDS website they do have them for the '06-'08 now. The Nautilus (judging by the picture) do not look "chromey" like the MSDS do.

MSDS includes ceramic coat at no extra cost. It has a bit of a 'chromey' look. But also be aware that he offers nickel coat at extra cost and the 'chromey' pic may be those.According to the MSDS website they do have them for the '06-'08 now.

Attached is a pic of mine as they arrived. (not quite as chromey in person)
btw- Marty is GREAT to deal with. the night before I decided to install mine I couldn't find the instruction sheet & cutout template for the alternator heat shield. Marty emailed me back somewhat late on a Thursday night with a copy of the diagram.

Did the headers make a big difference in performance do you get cel without the pre cats.

Off the line, not much. But when it starts building mid-range you can feel the difference.
I have no CELs... even though some say that's impossible. They've been on for quite some time not a one. (I do have a Magnaflow cat, but it's downstream of all 4 sensors)
MSDS for the win. Nickle plated was all they had when i ordered. It looks blinging until they get heated then they blue nicely. 06-08 are all the same. I just had to add the MIL eliminator that was supplied with the headers. I am also running a magnaflow cat downstream. I did have one CEL on a long 1000 mile each way road trip for bank 2 slow response. It popped on the first 200 miles, cleared it and have not seen it since. That was after over 10,000 miles of driving on the headers. And have since put another 4000 and still no CEL. Also... you can hit the speed limiter on accident once you add these, mid-high RPM just keeps pulling hard and fast to redline. An amazing improvement over stock. To get a little more out of low RPM I would suggest an exedy lightweight flywheel as well.
