Will do. I have the lower powered 2.5l motor. I make 175bhp stock and I dyno'd in pretty much right there last night. I have another session set up as soon as I can get free. Probably next week. I will share all the results.

I didn't use the stock manifolds except for measuring angles. These units are 100% stainless steel. 304 grade except for the flanges which are 409.

Set aside a decent amount of time. You may have done this before but here are the instructions per Bentley
- Remove Cabin Air Filter
- Remove Cowl
- Remove Brackets holding wiring to the cowl
- Remove Valve Cover
- Unbolt Coolant Reservoir and Remove Sensor Beneath it. Push to the side.
- Undo lower underbody panel. - Great to have removed in case you drop screws
- Remove Exhaust system - you can get away with leaving it on
You want a swivel joint on your socket at times and some deep sockets. You will need a small extensions as well. Some o2 sensors you can unscrew while others it is best to just unplug.
If you are using a bms downpipe fix, read the instructions carefully on where they suggest the setting to be. You can read it wrong and set it too low. You will get a CEL like I did.
