Joe:
Your comments were directed at me. Because of other commitments, I'm not always able to answer questions that are e-mailed to me as soon as I'd like.
First, a picture of the manifold IS on the Jannetty Racing website... take a few minutes to scroll through Ted's web page and you will find it.
Second, I did not buy the manifold from JRE; instead I bought it directly from ATS whose office is in Salt Lake City, Utah. The last time I visited their website I did NOT see it. You will have to give them a call. I assure you they have it.
Third, according to ATS the manifold was primarily designed as a replacement for the stock manifold which they said was subject to cracking on modified engines. That may all be true, but whoever designed it certainly had performance on his or her mind. The manifold comes in three pieces. the outside ends are an interference fit into the center section. You must use ant-seize compound to join the sections together. Assembly went smoothly and without a hitch. I believe there is some expansion and contraction at the joints and this in turn prevents the manifold from cracking. My manifold shows no exhaust leakage anywhere.
Fourth, the manifold is NOT cheap. As I recall, it's in the low four's and the Jet Coating is in the low one's. After reading these prices, those who are inclined to change their shorts should do so now.
Fifth, the reason I jet-coated it was to prevent if from rusting. I just can't see spending that much money on a manifold and having it rust out. Its appearance nicely compliments the rest of the engine's appearance.
Sixth, I don't know why anyone would want to cover the manifold with a thermal blanket because it looks just fine the way it is. But that's a personal choice.
Seventh, I doubt it has any effect on egt's but it DOES have an effect on performance! As far a mileage is concerned, I didn't buy it for mileage. I've always enjoyed very good mileage with my truck (21/25) so mileage was never a consideration.
I hope I've done a better job this time around of answering the questions that were e-mailed to me shortly after I posted the thread. If not, let me know.
