I lined the doghouse interior with Dynamat Xtreme and hoodliner, taping all the seams. Also put Dynamat under the plastic tray on top to damp down any vibration.
IMO it was worth the time and cost: Engine is less noisy especially when down shifted to higher RPMs. Noise quality is also improved by muffling the high frequencies.
Can’t say about the heat: Winter in Northern Michigan and ill take whatever meager heat the engine puts out.
