I recently changed me down pipes and I spent a week, twice daily dosing the exhaust nuts with wd40.... 7 were a bugger to come out and the 8th rung! If you have a precise blowtorch available use it to heat the nuts first (hopefully without burning the house down), the nut shouldn't need too much heat to get red hot then they should be easy to get off. Now I've gotta pay an engineer to drill out and helicoil my broken stud.... Sake!
