You can get Dynamat from any Audio installation place. I got the dynamat for my old E36 from Best Buy car audio section. It is a bit pricey though. I got a deal from my friend that worked at Best Buy. I think i paid like 30$ for a HUGE roll of dynamat. try asking around, prices might have gone down on that stuff by now.
