STIFF!
"I just got a batch of these installed today! My Forester XT Invidia exhaust was way too heavy for OEM rubber hangers. Once I installed the Grimspeed hangers the muffler could barely move! And the fitment is soo much better. *although I had to modify. These polyurethane hangers are super stiff, with very tiny holes. So I had to use a large drill bit and bore out until they would fit over the chassis and exhaust hanger studs."
