EBAY manifolds FTL. Full-race is the way to go imo i cant understand why people buy 30k cars and cheap out on parts.

 

How about the downpipes for Evo IX's? Do they actually fit? The pics have them looking just like TTP's.

 

I'm running both the MR O2 housing & the headers, I had them installed when I had my cams put in, they look exactly the same as the eBay ones. I've had them for about 6 months with no problems at all, 1 track day @ Sebring & two trips to the Dtagon, Deals Gap(275 miles in 2 days on an 11 mile long road!). I noticed good all around improvement w/ no loss down low. My car has a very nice sound to it too.
There is a lot of good stuff on eBay. I also installed an eBay FMIC, you know, those evil ones that are crap according to everyone except those who've actually tried them. I'm very happy with that too. I had my car properly tuned this time, a re-flash From Billet Design, that is way better than the custom road tune I got elsewhere! I'm making better power, no knock at all and I gained 50 miles to a tank of fuel while cruising around 90-95 mph!
I say go with it! Just because you pay someone more money, doesn't gaurantee quality! To get that, there has to be an apricable difference.

 

There are alot of good stuff one ebay. But alot of times they look like the same deal but in the end you'll end up paying more. If its due to price just wait a little more then buy something people are using and have tested.

 

I have the SS Autochrome Header and O2 housing. Both are of Stainelss steel quality. If you are looking for an inexpenisve way to add a little power I say go for it. The Header will require a little work to ensure it won't crack. Tack on a support inderneath and all should be fine.

I agree about the fast heating and cooling as both will glow red hot on high boost. I heat wraped mine and had a support tab welded on the O2 housing as well. My guess for the the Cracking issues is that the weight of the turbo and exhaust is too great for the thin walls of the header.

FWIW the EBay O2 has proven HP gains and minimal failures.

Do they make an improvement over the evo 9 o2 housing?
