Matt, given the length of the header and it's tube thickness, would you recomend header wrap to help with EGT through the length untill it reaches the o2 sensor (help increase o2 operation speed/warm-up) or go strictly with cermacoat?
Trees aren't kind to me...
currently: 2 88Ls (Scrappy and Jersey), 88LX, 90L(Pepe), 91L, 91GL (Skippy) 93 GL Sport (the Mighty Favakk), 94 (Bruce) & 95 Aspire SEs, 97 Aspire (The Joker),
94 Justy 4WD, 87 Fiero GT, plus 2 parts cars. That's my fleet.
Very nice job on the collector, Matt! You can tell its not just a cheap aftermarket with no thought of design!
Every header I've ever seen that had heat wrap put on it rusted out in short order if it was a street car and exposed to moisture at all. At least that's been my experience with header wrap.

Nice. I think ill order one in a few weeks. I am assuming that they are mild steel? Also, what is the average price to get coated?
I use high quality elbows & material which, if you have ever checked pricing, are expensive. To give a high quality header & still make it affordable, I am not offering them ceramic coated like jet hot or HPC unless asked for, as the cost of ceramic coating is more than the cost of the header.

Found header length to be optimal at 28 inch. Have experienced no O2 lagging problems, actually found on a mildly modified B3, EGT's in the collector went up indicating an increase in velocity & higher output engine helped.

Given the price of coating what do you think of header wrap and/ or that "silicone" spray for them? I know that people say that it can cause them to rust out but I haven't talked to anyone like your self as to the truths or fallacies of header wrap.

Typically I see wrapped headers rusting out when the customer wraps a bare mild steel header. Here in Indiana, combine that with rain & snow, they will rust. But, if a good high temp base coat is applied 1st & then wrapped, the headers will last a long time. All of my headers get sand blasted before high temp paint or ceramic coating. This retains paint much better & headers run hot anyway so it tends to keep the wrap dry if the car sits alot where it is damp, this would cause rust as well. I have considered making my header for you guys out of SS, but that would jack the price up considerably.
Regarding the tri-y question.....I experimented with try-y header on the B3 & found it to work well but in a very narrow power band & also mods tend to have either very positive or very negative effects on the performance. In all, I found the 4-1 offered the absolute best power over the entire RPM range & has positive results with a future mods that might be performed. Making it the best choice for this application. As tested, the header that I offer, really is as good as it gets.
