The Dynomax Super Turbo mufflers create an exhaust note that is too loud in the cabin of my X-Type. Has anyone experience with Dynomat sound deadening material put in their trunk/boot? Does this product work well?
Dynomat? Exaust sound in cabin too loud

Have you used a rubber or metal mount on the exhaust?
Dynomat should do a good job at deadening the sound if the sound waves are coming from the exhaust walls. If the sound is resonating from the rear of the exhaust then I doubt anything will quieten it down much.

Think of the exhaust like a cannon. Most of the sound will probably shoot straight out of the hole at the end of the barrel. Some sound will travel at a tangent straight through the sides of the barrel.
The best way I know of to silence a noisy exhaust is to add more baffles or sound deadening inside the silencer itself or add an expansion box nearer to the engine.

There's various spray-on & heavier weight products that will probably do the job, but a the trade off will be weight. A thick insulating carpet will put a good few kilo's on your car. I wonder if filling any voids, with an expanding foam might help reduce resonance possibly? :?
It might be cheaper & easier to buy some of these!
