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

I had the same issue and I also had to unscrewed the extended 02 bung and install the 02 senors without it. More then 1200 miles with the ERZ HFC and one night at the Drag Strip still NO CEL!
