I pulled out the OE stuff from my 1973 car to clean out the rust in the seat buckets and rear shelf. the jute layer under the rubber layer was pretty deteriorated, so I put Dynamat back in, then the usual rear upholstery. I'd say the Dynamat is pretty good at deadening sound, but the OE stuff was a little better, however the OE stuff weighs a lot more.
Net-net, I'm happy to have replaced the OE sound deadening with the Dynamat. If there's more noise coming from the business end, it's only when I'm hard on the throttle and high RPM. No discernible difference at moderate throttle or highway cruising speeds.
