My cat is cracked and Im thinking of replacing it myself. Is that something easy to do? Do I have to replace the o2 sensors?

 

not very hard but youll need the gasket and cleaning the o2's wouldnt be bad. Its tricky gettin that bottom nut on and off the cat<turbo flange.

 

question is does he have 1.8t or a 2.8. on the 2.8 you have to get it cut and welded

 

NO, its just a downpipe cat converter. It bolts from the exhaust manifold and goes down about 4 feet to the exhaust band clamp.

 

Nothing technical, just unbolt the old one and bolt the new one up. The hard part is just getting your hands/tools into tight spots to get at the bolts.

And no you don't need to replace the o2 sensors unless they are bad.

 

there prolly rusted on too, use some penetrating oil on the nuts and bolts the night befor you start.

 

I think my cats are goin bad too...i can really hear the putter when i pass things at low speeds with the windows open....and it pisses me off like no other. lol. Yeah Hiwords i kinda had an idea that the 2.8 was a cut and weld job. ****. wat u think that gonna cost.....

 

Tnx everyone. I have a 1.8t. Im also thinking of replacing it with a test pipe. What are your thoughts?
