Sounds a lot better with 4.4i mufflers vs 3.0i ones btw.

Good luck with the install, it's not that fun. If you are time limited I would suggest getting new manifold mounting hardware (studs/nuts to the cyl head).

Yeah, I was thinking about replacing the old hardware. It’s gone through so many heat cycles.

Overall I am very pleased. Highly recommend these if you don't mind going catless on the 3.0i.

Good job on the install! I highly recommend flashing the eu2 tune (factory euro catless tune). The exhaust smell will go down 80-90%, no cel, and you'll see a little better mileage. Without the rear o2's, the x is running pig rich as the ecm is constantly testing catalytic efficiency.

Did you do it yourself? I've been holding off as this is my daily while my project car is apart, don't want to accidentally brick the dme.

Yes, it's very easy if you're somewhat familiar with inpa/winkfp, etc. It's been a while, but if you have questions, post them up here, and I can walk you through it. There are lots of videos online as the process is the same for the e46, and a lot of those guys run the eu2 tune. The only difference is you have to select the calibration suitable to the euro version of your x.

I have those two programs loaded on an old windows xp laptop but am not at all familiar with them at all. I did awhile back test connect to my e53 no issues.

That's the hard part - getting the communications to work right. Since you've tackled that, you're ahead of the game. Flashing takes like 10 minutes.
