Just got my RM racing headers Ceramic coated the same white color as the Zonda

[BATMANs]

It's suppose to have the most ceramic content with a 55% thermal barrier.

Costs $300 for the set.

More updates later once it's installed.

A friend of mine that works at a very well known Aerospace and Defense company which I will neither confirm nor deny that he did the work using the latest and greatest....... :biggrin:

Hmm, I'm in the nuclear biz. Wonder if I can coat my headers with the ceramic from work - UO2?

My glow-in-the-dark headers would beat your white ones, and once I hit 88MPH I could time travel.

Anybody up for a group buy?

Why are there two O2 sensor bungs on there? For a NA1 car you only need one.

Good observation.

The reason why the seller sold the RM headers was that the original placement of the O2 bungs were not at the collectors.

I simply had it custom tapped and welded.

Was there a problem with where the original O2 sensors were placed? I ask because I have the same headers. I guess it doesn't make sense for the sensor to read only 1 cylinder . My car runs too good to change it now though.

By having the o2 sensor on only a single cylinder exhaust u run the risk of incorrect readings if that cylinder is off (bad compression, etc.). It may think that it's running rich and lean out ur A/F ratios and cause detonation.

Where can you purchase RM racing products through? I have tried searching for them on google but nothing pops up.

 

[BATMANs]

No longer sold.

Well that would explain it haha. Thanks for the heads up, I will stop spending countless hours searching for their website

RM Racing stands for Randy Marchetti Racing. I found a couple of Randy Marchetti's on switchboard.com and tried to contact them. Neither of them replied to my calls and faxes. His shop did a bunch of work to many NSX's and then he closed up shop and disappeared. I sure could use a copy of his archived records on my car because the PO didn't keep them.
Happy Motoring!

Last I saw on his website years and years back he switched to making stuff for C6 Vettes before vanishing. Maybe some of the Vette forums might know ...just trying to help. :redface: For all we know he is retired and sipping a drink watching the sun set somewhere on earth. :smile: I have some RM Racing DTM style exhausts. Low and loud rumble. Good stuff...in my mind. hehe

PS Out of curiosity, how much does ceramic coating cost on average and how long will it last?

Sounds like the common thing to do in the NSX community haha.

You can buy them new here:

RM bought their headers and exhaust from B&B, and they are still available. I have the exhaust and it is amazing.

What is special or different about the RM headers as opposed to say Cantrell, or others?

The RM racing headers seems to have a thicker neck at the collectors and after.

Also, the RM racing headers have a clip joint that allows some minor movement and adjustments to make sure the flanges are aligned for a better seal.

There seems to be a bottle neck with the Cantrell headers.

Thats a good idea. O2 bungs should always be on the collector.

The RM (B&B) headers are the only ones to use a slip joint to connect the header to the cats. A slip joint is basically a small tub sliding inside a large tube. This setup is extremely durable, but not as flexible as the flex-pipe or ball-joint connectors found on other headers, including the NA2. A drawback to this design is that until the pipe heats up and expands to form a good seal, the slip joint will leak exhaust gas.

The RM headers also have a larger collector design than other aftermarket headers, which makes them favorable for turbo or supercharged engines. The O2 bung locations are a drawback, since you're only reading 2 out of 6 cylinders, but many who run this setup report no issues. Plus, it is fairly easy to have a bung welded into the collector, as Batman has done.

As far as quality, my research has found that the weld quality is not the best or prettiest, as opposed to a Fujitsubo or GT-One, but the RM headers are virtually bulletproof. Many owners have had them since 98 or 99 and have no issues.

Thanks Honcho, informative answer!

I have had these on my NSX for 10+ years. Absolutely no issues. Honcho is correct they do leak a little at the slip joint until warmed up, but no big deal. Way better then a cracked flex joint.

So far it's holding up really good after 5k~ miles.

Didn't even clean it with this shot.

Notice how the ceramic coating didn't even brown or yellow.

 

[Ponyboy]

Have you performed any before or after temp readings?

I hadn't and wish that I had with my coated headers. I'm sure you could take some infrared readings off a stock NSX in your area as a baseline if you didn't do before readings.

Sorta.

Dunno what happened to the pics. Here they are reloaded.

This is a reading of the cats (uncoated) at idle:

reading of the ceramic coating:

So in theory if the headers weren't coated they should be hotter than the cats since the headers were close to the exhaust ports.

Those look great. I need to get this done to my celica
