Big thanks to the team at SF for taking care of my car last week.
I had them install eBay headers on my E46, which required new placement of the O2 bungs due to a design fault
Thankfully, they were able to get a shop to weld in the new spots without any difficulties. Couldn't ask for a more trouble free job considering the unexpected hiccup.
And to be sensible, I had the water pump and t-stat done as preventative maintenance which was also completed in a timely fashion at great prices!
