Started installing my downpipe today and the four studs into the turbo housing came off without too much of trouble; But the two bolts connecting the pre-cat to the main cat WILL NOT BUDGE! They have been soaking in WD-40 all day and nothing. My wrench is moving around the nut because of all the torque but the nut is moving. Any ideas would be greatly appreciated.


-Could I just install a midpipe? Would this be safe with a stock exhaust and stock ecu. The dp and mp would be my only mods. TIA

 

You should get some of this stuff... I had trouble with my precat bolts a few years back, and PB Blaster made things easier. Just spray it really good and kind of tap it with a small wrench or something. Let it soak over night, and try again.

I've only encountered one bolt this stuff wouldn't budge.

 

man i had the same problem, i just soaked the nuts with wd 40 for a while. The nuts ended up coming off cause i got mad, took one of those big adjustable wrenches and actually started kicking the wrench out of frustration. Then i tried this, and i found out it worked pretty good cause it stayed on unlike the wrench eventually freeing the nuts http://www.sears.com/sr/product/summ...id=00942154000

 

Use a box ended wrench or a 6 point socket. Slip a pipe over it if you need more leverage. Shouldn't be that hard to remove.
