I'm going to install my new berk hfc tomorow and I want to know if you guys have some tricks to remove it the oem cat...

How to remove the three bolts that fix it to the header???

thanks

 

a loooong extension and universal - and get to them from the engine bay. well, the top bolts - the other 2 can be had from under the car.

 

soak the bolts with PB blaster overnight so they come off easier.

 

This.

And IBtylerxfire says you don't need to do it from the top.

And also may want to just get new gaskets the first time around. (I did not and had leaks so it was basically the same job twice)

 

Here's an excellent how-to video: http://www.youtube.com/watch?v=bH9irOK9sdo

 

yup i do them from the bottom and have done them 3 times now and a 4th next week...my berks failed twice so i gutted them out and now they are cracking so berk is replacing them with their test pipes and ill be swapping again...i do them all from the bottom and there is only 1 bolt that is fixed to the header the others come out..just do it and get a bunch of different extensions and some bars to extend ur ratchet for more leverage is what i do.. u will need a deep 14 and a normal size 14 mm socket and a few different extensions to play with..16mm wrench i beleive it is also

 

Hints: Spray all hardware with penetrating spray the night before.

 

ya, do the driver's side first.... i just helped a friend out tonight... the top bolt is blocked a little by the steering shaft/column.... if you can get that off, the rest will be a walk in the park

guess which one we did last

 

def. do driver side first and get it out of the way...also remove the bar that goes across and bolts to both cats brackets u will have more room...i just changed my high flows out for test pipes yesterday once again..toook about 45 mins. start to finish

 

you can also heat the studs with a torch to crack the rust off of them

 

Are you still under there OP?

 

thanks guys it's done since yesterday lol

according to me the best way to unscrew the bolt facing the engine bay have been to pass by the engine bay with a long long long extension like Skingy said the others bolt were very easy to remove... <

thanks again to all of you for your help
