Each kit includes our state of the art "2 piece" turbo manifold produced by
"Steed Speed" specifically for the E46 M3. Each turbo manifold is literally
carved out of a large chunk of steel with each individual section welded
together. There are several reasons for this incredible design. #1) Assembly
takes 1/4 of the time as the head flange simply bolts right up without any
interference, then the main section is bolted on with 4 bolts. #2) There is no
chance of warpage or cracking with this manifold as opposed to tubular manifolds
that tend to warp and/or crack over time as the pipes and the flanges have
different rates of thermal expansion. #3) Each manifold will be exact in every
dimension to precisely .001" which is just not possible where individual pipes
are cut and welded together. #4) Every runner has an individual path directed to
the turbo flange. These short clean runners provide the ultimate quick spool
characteristics. Top end power is also improved over a comparable log style
manifold as each runner follows it's own path the turbo as opposed to all runners
going down the same channel. #5) This manifold directs air flow from all 6
runners into the wastegate. This is not possible where merge collectors are used
on tubular manifolds. This allows the computer to ramp up boost much quicker as
the wastegate can remain closed until the last possible second and then opened
quickly without creating boost spikes. #6) In addition to manifold design, every
manifold is also ceramic coated to keep under hood temperatures at stock levels
retaining factory under hood conditions.

|The HPF head flange pictured below bolts directly to the head and|
connects to the HPF turbo manifold with 5 easy to access allen bolts.
This makes installation a snap.
