That thing was a pain in the a$$ to remove.
Luckily I had a o2 sensor socket and a braker bar.

I made sure to put anitseize on every thread..although I accidently put some on the o2 sensor itself.
I cleaned out pretty good. Hopefully it doesnt mess up anything.

With the new parts installed, the sound is slightly louder @ WOT, but I like it.
It's a lil bit louder than before but I like it. It's not too loud.

The boost comes in slightly quicker and seem to have better respond.

I put about 100miles so far...hopefully no CEL comes on.
I did the anti fouler method.

All in all, pretty happy with new parts.
Now I just have to get it flashed to wake up the beast.
