Racing Dynamics m20 e30 headers

That was included in the initial 1300.

Frank would be the person to answer the downpipe refund question....I would like to know it myself.


If I understood this correctly, coating was always extra to the initial 1300 though.

If anyone changed their mind and doesn't want their set anymore, or if there's an unclaimed set Frank :thankyou:

Did you pay for downpipes too?

The guy who sold me the coating said it was lol.

Seriously though.. a quick search yielded this in reference to stainless VS mild

"But chromium atoms that are mixed in with the iron have the added effect of making the material worse at conducting heat than mild steel"

If it's worse at conducting then it does give off less heat. Whether the difference is significant enough to call it a thermal barrier I have no idea and about how much the coating helps, I know even less.

It is pretty though :)

the question of whether a coating does anything or not to stainless steel is not really a question of whether 304 stainless steel is better than mild steel, as stainless is known to have a lower thermal conductivity and lower emmisivity so the heat transfer will be lower with stainless.

a lot of the ceramic coatings are nothing more than glorified VHT. the aftermarket world is full of smoke and mirrors without any real test data but the best ones to use are zirconia based that are plasma sprayed and they have some body (thickness) to them and therefore affect the conduction through the pipe wall. i think swaintec white lightening might be one of those that's what id be looking at but black if possible to avoid the grubby finger prints...lol

i personally think it looks much more presentable after coating especially on something where the fab quality is not up to scratch. Done properly it seems to last alot better than VHT paint, and any improvements in thermal control of under hood temps are a bonus ( it does still seem to help though). To protect components from the radiation a thermal heat shield is the best thing you can do but this conflicts with presentation.

We all paid for downpipes per the initial GB info.

Got my headers yesterday too. Paid for coating and they arrived uncoated. Are we going to get a refund for that?

Bingo!!! SS can be made to look nice too but maintenance of that look will be a pain...considering the location

Racing calipers often use stainless steel pistons in order to reduce heat transfer from brake pads to brake fluid...

Stainless steel is already a thermal barrier. Unlike regular steel. Therefore, I really wonder if ceramic coating them is really needed. ;-)

I don’t know if it’s been mentioned but what material are the headers made from. If it’s stainless instead of mild steel I would forgo the coating if that’s refunded. If it’s mild steel they gotta get coated in something if they will rust.

I wound up with OE RDs which are stainless. I had them coated based on the supposed reduction in heat so there's that to consider

Shipping out a few sets today and a remaining sets next week, sorry but been swapped at work.

Who won the lottery last week guys? Remaining losers, what is the chance we get a tracking number tomorrow?
