Removing cat bolts to fit milltek-Help please

[bertman]

Just recieved my cat-back Milltek,lovely looking piece of kit and a big thankyou to pete at quattro corner for sourcing me the zorst after another forum member snaffled up the last one pete had....you know who you are!
Anyhoo I am sure there are people who have done this themselves and come across the horrible bolts on the cats.The only way I can see to get the bolts out is to take the whole cat assembley off and cut the nuts off and then drill out all the holes so new bolts can be fitted.Why Audi spot welded the nuts onto the flanges is beyond me
All the nuts and bolts are very corroded,some have nearly rusted through completely.Looks like it's going to be a right pain in the bum area,but have all the tools I need other than a nice ramp to work under
Any help or short cuts will be greatfully appreciated
Cheers
Rob

cut´em and buy new ones,

Cut them off with a good hacksaw or grinder.

Thats what i did, it took a while but was worth it.

When I took mine off to do my clutch they were by the sounds of it like yours. I cut them off with an air cut off tool but even when I ground the heads\nuts down I had a job getting out the studs that were left. Ended up having to drill a wee dome into them then hit them with an air chisel with a pointy chisel.

They are a nightmare, just cut em out and renew.

Job done
Exhaust sounds and looks the doggies danglies.Cat bolts off the down pipe(after a good soak with gt85)came undone and thankfully none snapped,this allow to work on the cat bolts.cut them off with a cutting disc and then punched out remainders.
Only real prob was one of the rear exhaust hanger bolts snapped off,solved the problem by welding another bolt onto the tip and the managed to unscrew.
Started at 10 am and finished at 3pm,not bad without a ramp
Back blooming hurts now,nothing working on concrete

Loved to have had it sitting under the tree Al,but unfourtunately the tree is only about 2 feet tall,so the boxes would have looked a tad massivePlus it would have taken about twenty quids worth of wrapping paper to wrap them up!
Anyway no better place for it then sitting under the car:mischeif:

Nothing like a decent Milltek.

Well done!
