cat delete pipe broken bolt

[Steve Tinker]

Meir..
I'm in Australia - we have ROW specs where only one set of cats and O2 sensors are fitted, both mounted in the pipes just prior to the muffler. The exhaust manifold is just that - a manifold without cats / O2 sensors similar to US 1997-99 2,5 models .....

Che's cat delete pipes for 1999 - 2004 S models don't come with O2 bungs in the pipes for me to fit the sensors, so I have to weld them in.
Perhaps I should have purschased the Che's 2.5 pipes which have to bungs already installed......

If you are talking about the triangular flange where the header meets the exhaust, those are more like splined, press fit, hardened studs. They can be removed by using hardened titanium twist drills. Work by progressing from smaller sizes up till you reach just inside the stud diameter, then tap out with small drift.

the bottom 2 are studs but the top of the triangle has a welded nut. i think they did this on the 03 , 04 cars. as for taking the axles out , it would make the job a lot easier and less messy . i would have taken the axles off if i was going to replace the wheel bearings . pumping myself with coffee to build up some steam to finish the job . also gonna change the plugs and tubes while i am already in there .

a little trick that helped me out . the cv boots can be tough to get on. i heated them with a hair dryer , they went on a lot easier warmed up. then again it is not exactly warm hear in massachusetts in my unheated garage.
