More details are coming soon on the release.

The options for ordering will be:
1. The manifold only for $1900
2. Hot parts only kit (manifold, 3" downpipe, 2 dump tubes) for $2200
3. Hot parts, coolant relocation pipe, intercooler pipe, the heat shield & AN adapters for oil feed/drain, coolant feed/drain, block off fittings for $2500.
These parts we are still working on, I will provide more photos next week.

The kit uses two 38mm tial waste gates, 3" downpipe, T4 divided turbo flange and bottom position O2 sensor bungs with heat sinks helping them to avoid burning.
We give a 10% discount for the first 10 customers.

Seen it on e90post as well, was gonna comment but meh.

Whats the difference between this and a doc kit? Other than o2 placement, which may be worse being closer to the heat source, dont see much of a difference, other than its about a 700 cheaper for the complete hotside kit which is better, but not if it eats o2s.

Multiple tests proved that upper position is bad due to the lack of cold air flow letting O2s just bake. The combination of heat sinks & increased ram air flow should help a lot.
However, only the real tests will show, they start next week.

Would have been nicer to seen a v-band flange for the turbo instead of just another T4 top mount.

The bank 1 wideband hanging upside down like that is going to kill lsu 4.9s and ADVs from moisture accumulation around the ceramic element. My original design was like that due to space limitations. Ended up going single bank downpipe because there was no way around it without rebuilding the entire manifold, lack of space in rhd in my case.
