on land rover its exhaust off every two years to install a new dpf , or cat , or turbo , or filter at the turbo , etc etc etc ,,, on the bright side the nuts dont seize once you do them once ,,, in fact you could put the exhaust on with velcro its on and off that often.Nope not really. Stainless likes to gall and seize, too, and does corrode with salt and heat.
Titanium costs a bit more.
Just use decent steel bolts and expect to replace them each time. How often does an exhaust need replacing, 20 years or so?
