S52 swap - Exhaust manifold?

[ScottCantStop]

Hey guys
I've got an 89' 325i sedan at my buddies shop, currently being resto/rebuilt and s52 swapped.
We grabbed up an m50 intake mani from a r3v member, waiting on ground control coilovers to come in. While we're waiting, I'm ansty it's been almost 3 days since I bought something for this car -- So I'm shopping for an exhaust manifold.

Is there any significant gains to be had with any particular exhaust manifold for the s52? Shop will be building a fully custom exhaust from the manifold back...

Any recommendations?
Thanks
S

There isn't much to be gained from bolt-ons. The S52 is what all the M5x guys bolt on for some gainz.

A lot if people run ebay long tube stainless headers. But I went with stock obd2 manifolds with sap block off plates because most people said the long tube headers are very raspy.

thanks for the responses guys. lookin like we'll stick with stock for now. perhaps in the summer if/when the s52 gets turbo treatment things will change....

+1 on the stock manifolds. I took my longtubes off as they were fairly raspy but they sit right on the control arm bushing and vibrate like a bit*h. They do free up some power up top and loose it down low vicsa versa with stock.
