Finished up over the weekend I just ordered another sheet of Dynamat hoodliner so I can line the area just above the transmission for heat insulation. We put the Noico sound deadening on the doghouse, above the transmission and on both passenger and drivers side, then put dynamat hood liner on the doghouse and around the doghouse opening. Decreased sound by about 5 db at 2500 RPM while parked.
