all stainless corrodes. some just resists it better. heat + welds + chlorides will take down stainless rather easily.

 

I'd always heard that you do not want to wrap stainless header pipes as you had a higher chance of cracking the welds. Stainless expands a decent amount with heat. Holding more heat into it would only make it expand more.

 

the header on my miata was ceramic coated inside and out with JetHot and then wraped, even after a hard run, it was hot, but you could touch it, and kept the head inside down.

 

Granted I was only in metallurgy for about one semester and have only welded all types of metals and alloys for 8 years, but what I have learned is that stainless is just that, "Stain Less". It is not rust proof, it is only treated to prevent rust, not stop it. It is very smart to apply a rust prevention coating or spray paint rusting on your pipes if they are going to be wrapped or exposed to salty areas. Be smart with the money you invest in your vehicle.

 

welder --> mechanical engineering degree --> engineer in industry that uses stainless exclusively in it's processes --> sales engineer for stainless steel process equipment manufacturer

I deal with this day in and out, it's unlikely that you will shed light on something stainless-related that I don't already have direct experience with

It makes sense to invest in things in which you personally will see a return benefit from, hopefully somebody 50 yrs from now will appreciate the thought.

I wouldn't have done it that way, but that's just me ... it wasn't my intention to hijack the thread.

Is somebody actually going to install the d*mn thing????

 

well I've seen the results of corrosion on austenetic stainless steels. Sure it corrodes much less than carbon steel, but it corrodes (sometimes catastrophically). Bending it, welding it, heating it, and exposing it to corrosive environments aids its corrosion greatly.

 

Will post results friday iam guessing 4 to 6 hp will see

 

Aren't most of the aftermarket headers stainless steel? If not stainless steel, what is a good metal solution?

 

Does anyone have any feedback on the sound difference with this header or any header?

 

no one has it on yet.

beers

 

hmm.. I'm really skeptical about this header , weather it's going to give decent amount of power or not...

I think 300 bucks for 5+ not really worth it then again if you are one of those guys that need every little hp out their. Well then i guess go for it... Wait i think i kinda fall into that category!


I just want to see some dynos on it =]

 

I already dynoed my car at the same place so I will know how much i made with out it.I'm also adding a piggy back ecu. My goal is to dyno 230 to the wheels with the nitrous on.

 

hey sergio didnt you tell me that you got more than 230 before?

 

Not me i keep everything a secret lol never even posted my old dynoes but will now

 

so did install the headers yet?

 

I should get the car back tommorow

 

oh i thought you did all installations yourself...where'd you get it done? i asked all over the places and got shot down alot

 

mothers performance 400 to install just the header i was going to do it myself but got lazy .are in NJ too ???

 

hahah yea man...you sold me the hiflow past summer =P

 

dayam....400....thats fucken crazyyyyyy...makes me think its not even worth installing it

 

yep tell me about it

 

did you ever get anything done to the car ??

 

yea i got the aem cai, switching to b&b midpipe that i just got, got rims, nology wires...

 

SO how much damn WHP did you get ?

 

no one got it installed and dynoed
