Removing cat clamps?

[haste]

Hello,
My entire exhaust is off, except for I have no idea how to remove those 2 clamps on the cats. Then it's off to remove the 2 rear muffler bolts :0


Any help on these last 2 items?



Also side note, are all wheel spacers technically the same. What's the difference between cheap eBay spacers vs the 80 dollar a peice units?

The hangers or pipe couplings?

The clamp with 2 bolts - the one that connect the secondary cats to the muffler?

Those just need to be expanded and twisted. Use a LOT of penetrating oil in there, maybe even let it sit over night. I flooded mine, waited a bit, and then used a flat screwdriver to spread the clamp. then aggressively twisted back and forth and it slid off...

We'll I really just want the muffler off. I want to keep the 2 u bends into mufflers.

I went ahead and removed everything. I just cannot get that clamp off the clamp with the 2 bolts after cat. Neither can I remove the one clamp into muffler. It soaked for a day. Help?

As I recall, you loosen the bolts, twist it side-to-side, and then slide it back on pipe.

The U tubes have to come off the 2nd cats/muffler to get them out.

also the 2nd cats have 3 nuts/bolts to get off.

you of course have to disconnect all the bracing and loosen the muffler hanging bolts as well for the jiggle freedom at the U tubes.

Once both ends are released you can jiggle it out towards the rear of the car.

I used a lot of WD40 on the bolts and the U tubes on my SOCAL car, but I imagine in more wet climates more drastic measures may be required to free things up.
