either a 3/4 or 7/8 wrench (can't remember) works a lot better than an impact!!!

Lol it's 7/8" and I tried to get them out of the original pipes they wouldn't budge.

Lesson learned

Lesson learned

you need a nice long wrench. if that doesn't work, you can hook another long wrench on the end of the first wrench for more leverage. also, sometimes it helps to have a hot exhaust.

When we remove an O2 sensor a friend's car, the sensors threads were galled so we had to replace it. It took an huge amount of force to get the original one out.

Also it had a misfire CEL. I set up HP Tuners to count misfires by cylinder and it was a plug wire not seated. Rear drivers side.

Yes video please, I'm sure it sounds pretty sick, by the way I'm glad your car is running the way it should.

I've taken two with my iPhone and you can tell that it's louder than stock but it just doesn't capture the sound very well. I will try again with my external mic on my actual 1080P camera, and maybe make a GoPro video.

I will post up a link to the video when I get it done.
