I am interested in your sound deadening efforts. I find the tyre noise on course grain paved highways really annoying. Some of Melbourne's freeways have much smoother surfaces which means quieter inside. But I do not have the skill nor inclination to install sound deadening myself & am not sure who or where to get it done. I am also interested & upping the exhaust sound (which seems like a contradiction!) as I like the WRX sounds.Cheers Gents.
After near on 1000km's done since installation the system has settled down nicely.
I was abit apprehensive at first about the potential 'drone' noise yet this slight 'in cabin' sound has calmed down to a feasible comfort level... hardly even noticeable now.
Prior to installation i used a sound deadening product in the tailgate/boot area. The start of limiting both road & exhaust noise and definitely worthwhile.
How much & where did you get your sound deadening done?
