I bought new OEM hardware just in case the old was in bad shape, the existing hardware was 100% fine so I reused them.

would you say the guide by Turner is pretty accurate to your install experience? (this guide = http://bd8ba3c866c8cbc330ab-7b26c6f3...stallation.pdf) |

I never would have tried to the my f30 awd car. it was way too troublesome for me to try. I did my CP, IC and turbo Inlet on the f30 and that inlet was a huge pain in the ass.

Did catless DP on my N54 E82 before getting my F25, it's not a complicated thing but can be tedious. Best to disconnect the O2 sensors above by the way. Just crack the pre/post O2 sensors from below then pull the whole thing out including the sensors and wires. If you don't, the wires will end up twisted, and I honestly found it easier to drop them with the sensors anyway. I was able to torque the O2 sensors to the new DP out of the car, just put it in a vice or wrap one end in a towel and use a foot to keep it from moving while you torque the sensor with a crows foot adaptor.

finally got around to doing this. took about 3hrs on a lift. had never done one before so it was a learning process. it was difficult but easy at the same time.
did a video and will do another video comparing the before and after 1/4mile times on a bm3 stage 1 flash.
