Stiffer exhaust springs?

I'm talking about the springs that hold the full termi exhaust system together. Do they loose their power after a time? Can I get stronger replacements?

I haven't noticed that my springs have gotten any weaker. Never really thought about it. You could always double yours up, if you're worried about them

i've snapped a few due to the awesome power put down by the Hotrod M944. go to your friendly neighborhood Honda dealership and get the expansion chamber springs off a CR250 exhaust. i have 2 on the header now and they have stayed put. Cost is like 8-10 bucks.
