DIY: Berk Technology HFC Install

kbc749

Thought I'd post in here to tell my Berk HFC install story thus far,

Today I spend about 2 hours trying to get the Stock Cats removed, using 3/8th inch extensions and several 14mm wrenches and sockets, and plenty of penetrating oil.

Got all of the bolts broken loose except for the two cursed bolts facing the headers and one of the two O2 sensors was being stubborn. The two cursed bolts wouldn't turn with the 20" worth of extensions, all of the torque was just lost in the extensions twisting, (even when I got it down to just 1 extension).

Also one of the O2 sensors didn't want to turn out, it broke loose and then stopped rotating, to the point where I started to round off the corners of the bolt, not sure what I'm going to do about that, put some penetrating oil on it and will retry.

After reading the full forum post, I went out and purchased some 1/2" extensions and am planning round 2 on Thursday Afternoon. If your reading this and going to do this mod, take my word for it 3/8" extensions are not good for those front facing bolts.

If anyone has any further suggestions, feel free to quote me. Thanks!
