The second O2 in the system is just to check function of converter and it can be removed and turned off in the calibration by the tuners like Mike at Motoeast.


Thanks Brian...that is what I thougt. The one is referring to was the downstream sensor. The upstream was fine!

Thanks for this writeup. The tip to move the alternator was invaluable at saving sanity. I lost quite a while wrestling with a corroded heat shield bolt, but other than that this was an easy, straightforward project. But not a quick one. The header frees up so much more power even before the retune on my Cosworth SC setup. Really satisfied with the product. Thanks, Brian!

Gentlemen,

I have completed this install about a month ago using the ceramic coated header. I would prefer to remove the heat shield that remains, but I can see where keeping heat off the brake lines would be an important factor. However, my temp probe even after hard driving remains much less than my coworkers readings for his non-ceramic coated header. Would it be dangerous/ill advised to remove this remaining heat shield for aesthetic purposes? Has anyone noticed where the temp was "too high"? I don't have a good feeling for what "too high" would be for exposure to the brake lines.

Thanks for any help!

I don't expect any issues on street car using ceramic coated version, but heating the brake lines certainly won't help anything. Since I have no reason to test without that shield, don't have any data to offer.

Not a good idea because the way you find that out is that you're driving hard on a hot day and suddenly there are no brakes when you step on the pedal because the fluid has boiled. And since you're driving hard it means a very hard crash from high speed.

If you really hate the look of that heat shield so much, why not polish it or chrome plate it or tint it or do something to make it special and match your under hood decor? Just keep it in place so the brake lines are protected from too much heat.

Cheap solution is barbeque paint, high temp and will last.

More fancy solution is have it powder coated your color of choice or use header paint in your color of choice.

Thanks for a BEAUTIFUL product, Brian! This header is fantastic! I cant get over how much extra sound it adds to the exhaust, but my engine and I thank you for letting her breathe! This setup (Header -> Midpipe -> MS Muffler) has really turned up the rev factor, and I love it! Ceramic coating looks great, too.

Installation (incl the midpiep) took about 4.5 hours total, but that was working at a liesurely pace. It was about 3 hours getting the header out. It LOOKS like it should just slide right out but...

I'm sure others have mentioned it, but if not, you MUST remove the bracket that attaches to the engine block from the OEM header before trying to pull it out. Even with the alternator tipped forward the bracket prevents removal--despite your eyes and brain telling you otherwise. These two bolts were the only one that were rotted on, so they broke as I took them off, but you dont need the bracket anymore, so it doesnt really matter.

Again, fantastic build quality and craftmanship, Brian. These pieces are works of automotive art!

Thanks for all you do and keep the innovation coming!

I'm planning on installing the RS Max power later this year. The above statement and a previous statement about you reflashing your wife's ECU and gaining 0 HP from the reflash has me wondering if I am missing something.
Did your wife's car have a tune BEFORE you tried tuning again after the exh install? If so that would be more understandable than no gain over stock ECU settings.
From all I have read a reflash is a good HP gainer over stock even without exh ugrades.

Hope that wasn't to word-dy.
Thanks.

The wife's PRHT was on stock tune when header was installed. But there are about 25 different stock tunes from Mazda, many seem to auto tune to the new header perfectly every time, some don't. Thus, on some cars the added tune doesn't add much, on other cars it adds a lot more.

That's super interesting. Any insight on which years feature "autotune?"
