I (barely) managed to get the 2 nuts at the collector end out with an impact wrench so that problem is solved. Torching it did not work as well, $400 later and 1,100 reverse torque impact wrench worked it's magic.
The first 13mm nut at the engine block end was ok coming out (Pic 1) the rest are all rusted tight. I took the impact wrench to the lower ones and the stem from the engine block came off with the rusted nut still in place!, see Pic 2. Can I just put some red loctite on there and thread it back into the engine block or is this a bigger problem?? Thanks.
Edit: Not an issue, the spindle comes out and new bolts from the manufacturer go in.
