Obie, yes it is surprising how long it takes. I poured oil over the rockers before starting and that was after an overnight soak in oil.

Nippy mog, I have the AR Stage 1 pipes too, but I finished boring out the oem mufflers so I plan to swap to see how it works. Nobody here to adjust the locked ECU so I will see how well the self mapping goes. I suspect that it will work ok but a retune would undoubtedly be best.

The ease of reving was evident just sitting on the lift. Usually it would cough a bit but not now.

The light at the end of the tunnel is actually a train. 2019 M3W
