Yup, I put layers of Wurth (Sound dampening material) + Superlon together...
My Iswara now sounds more solid... Of course can't compare to continental cars, but at least sounded more solid like WAJA.
Should have known Ninja earlier, cos I bought those Superlon at a slightly higher price from a hardware shop.
Only one more problem now... tire noise.... already about 70% worn... maybe need to change the suspension system bushes as well..
