[Boostedexcel]

Does anybody have experience with these manifolds? I tried searching but couldnt find anything, here's a link-

It looks just like this one...

Which is cheaper, and it's even bulletproof!!

I would go with the cheap one off of Ebay that xioca has a link for. But thats because I like trying out the cheap items when its just pipe or non-mechanical in nature.

Are just saying that its bulletproof because of the add or do you have one of these?

Let us know if the megan racing crack, which i know ebay will already

I bet the ebay unit has mild steel flanges. I ad says the flanges have been chorme plated. There is no need to chorme plate S.S.

I was poking fun at the add. Also I'd go with the ebay one, just brace it. Worse comes to worse and it cracks reweld it, hell if your worried about it have it rewelded as soon as you get it.

Also why does it matter if it's SS. Mild steel is stronger, and seeing as it wont really get wet to often unless you let it, you should be fine. You could always have it hot jetted if your worried.

Anyways if you really want to know if it's really SS just ask the guy.

megan is starting to look better

With the amount of heat cycle an exhaust maniflod see and the different expansion rates, this very hard on the welds. They will fatique much quicker. Also I don't agree that mild is stronger than Stainless.

I would contact them to see if they offer any kind of warranty. After reading about all the good experiences people have had with exhaust-related megan racing products i'd say go for it.

I'm fairly sure that mild steel has a higher temp. rating and would be stronger in tubular manifold applications. I'll look it up tomorrow to see where I've read it from. And a weld is a weld, if it is done properly that is.

Thicker mild steel is "stronger" due to the extra materal (I.E. weld-els) but for a given geometry of material SS is stronger. Also, SS retains it's strength better under the higher temperatures. With proper turbo bracing none of that really matters anyway as all of them can pretty much support their own weight until they are nearly liquid. It's when you have a 20-30lb turbo and god knows how much exhaust weight tugging at it that the problems start. Other problems w/ cheap maiflds are the welds sealing, and I've heard junk from poor gas coverage on the back of the weld can chip off, but I've not seen that in person, and my turbo still runs fine after eating 3/4 of an exhaust valve

You are right, the cheaper header's flanges are commonly plated and of a lesser alloy than the tubes or mild steel. It will wear off and look crappy, but from what I've heard, as thick as they are, it's not a structural issue.

There are many cars making A LOT of power with mild to stainless welds. It came up as a topic on turbomustangs.com one time and there really isn't an issue with welding mild to stainless as far as durability goes. Actually I think the resulting alloy was more ductile allowing the welds to survive longer. Search over there, the welding guru laid it out much better than I can here.

They look exactly the same to me, and if all the welds are like that... well that's much better than I could ever hope to make. Go with the cheaper one!

You get what you pay for. I'd make sure to brace either of them before I hung anything more than $200 off of it. I'd also not run a $1200 turbo on it. Just not worth the risk of something breaking IMO. That would be like a ferrari on pep boy tires, just asking for trouble with expensive toys.

I'd go on, but you see I gotta run. Miss BestAutomotive 2006 wants to go drifting in my AWD Talon. She looks just cracked out enough to believe that was possible...

 

[Boostedexcel]

would I be stupid for running this cheap mani+cheap turbo on a built motor?

 

[Dream On]

Turbo, yes, manifold, no. The manifold shouldn't hurt anything should the welds fail. The turbo could do some damage though.

Megan may be inexpensive but they have good quality parts. The get what you pay for really doen't apply like it used to. Look at the ebay fmic!! To me Megan isn't trying to make a 300% profit from there name like Greddy or HK$ or some of thse other vendors thus there prices are great. I have there 3"ss dp and it blows the twice as much Apexi which is only 2.5" untill the flex section then it's 3 and not even ss. Talk to the evo guys that run there manifold and see what they say.
