Well they don't have a large enough bore to fit the O2 sensor! I tried to drill it out but only had up to 1/2" bit and it wasn't enough. So I had to install everything without them. I'll see if I get a CEL...

The inlets on these looked much better than the previous set. I'll post the pics up tomorrow and take some video this weekend.

I took it for a spin and all my frustrations of the install and the O2 bung melted away. These things sound awesome and I can definitely feel the bump in power. I couldn't be happier with the performance so far. Only took it for a 20 minute drive but so far so good. I'll update with more driving impressions later on

Have someone drive your car away while you are standing there....sounds sick from outside!!

BTW - I had the same issue with my O2 extended bungs. I proceeded with the install without them. I have put about 400 miles on my car since install and no CEL
