Tell something about your setup and/or goals, you can get better suggestions that way. But if you just want some "fun", the stock turbo manifold should be enough for quite some fun.

The only readily available turbo manifolds are the stocker (easily able to handle 350hp, maybe more) and the cheap eBay manifolds (but they don't put the turbo in the same place, so the exhaust doesn't sit properly).

If you don't like those options, someone will have to make you one.

Just get one made to your liking and by someone who is competent enough to provide you a solid and reliable product. All of my cars have custom manifolds that were in excess of $1000 US each, so if you can find something functional, yet cheaper and fitting of your tastes, then a custom manifold will be for you.

That's still an eBay manifold. Exact same thing.

Yes, and i doubt that its 321 steel.
The best china option is the OBX one wich they claim is made of 316.

i'm using cheapo Ebay ex manifold since 2009 i think .

i have machined the surface that connecting to the head and done a support from bottom to turbo flange to prevent cracking on high EGTs .

It needs machining because chinese guys do welding to the big flange but don't think if it is expanded by the welding heat or not . i have found that there is 3 small hills on surface .

if you change from OEM manifold to ebay manifold you will lose some response on your turbo and maybe 300-400rpm lag will be added to your spool up time . But your Max torque RPM will go 700-800 rpm higher with long runner manifold .


Consider your needs and spend your money wisely. If i were you i will go to the end with stock manifold .
