Headers for 330i

I'm looking to buy these headers for my 2002 330i. Will I need to make any modifications to fit the O2 senors like other eBay headers? And in general, is this a good choice for headers?

I have the same headers on my 330ci.

The fit and finish is top-notch.

The pre-cat O2 sensors would be an easy fit. Impossible to install post car O2 sensors as the bungs location has serious interference issues. I had plans to run foulers because of this issue decided to go for the O2 delete software from AA itself.

Tip: Use stupid amounts of anti-seize and nickel coated nuts for the manifold bolts when you reinstall.

Since your 2002 330i has the MS43 DME, you can just flash in the EU2 software (for free) to delete the post-cat O2 sensors and SAP system. I do this remotely for people on here all the time. See link in my sig below.
