Questions regarding Headers: Nautilus or MSDS for an '07

3690 Views 8 Replies 7 Participants Last post by  06m6v6
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.

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. :confused:
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.

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)
