It depends on the level of noise you're dealing with. The main reason why people replace the gasket is that it is more durable, being double thickness. I've had a lot of new orders and a good percentage are from customers upgrading. I have had a lot of comments from these new buyers that they like the new gasket much better and that they have noticed a greater reduction in noise. I'm sure every car is different. I can tell you, though, that the new gasket is just plain more durable due to it being twice as thick. I think you'll like it.
