Besides the DP's and the DP to exhaust gaskets and DP to exhaust bolts, is there anything else required for the install?

Can anyone recommend non-standard tools that will make the job easier?

o2 sensor socket is useful, nothing else i can think of... maybe some pb blaster for the bolts.

Thanks! Got both of those. Is the O2 sensor the traditional 7/8" (22mm)?

Haven't done it in a 335i but a breaker bar makes life easier.

Used the same tool.

PB blaster, Stubby ratchets, long extensions (12 inch or more), cordless impact, and ratcheting wrenchs with flex heads. There's a good video on youtube by AR Designs (I think). I highly recommend watching it and following their lead. Did mine in a couple hrs on jackstands.
