Just wanted to swing by and say hi to everyone here! Been lurking for over a year now and decided to actively participate in the forums. I've got a '12 Prius II and love almost everything about it except the extremely loud road noise. I'm planning to do the whole dynamat project for the interior next month. I picked it up used with 15k miles in JAN 2013 and now approaching 90k miles thanks to yearly trips to Utah and SF. Things drives great. I'm coming from a Tundra Double Cab, the $$ saved from the pumps is so heaven.
Thank you, sir!! I'm looking forward to the potential improvements! The noise is coming from all over. A lot of noise from the ceiling area to the footwell and doors. I'm using Starfire tires...they were free and handle decently fine without much road noise at all. I just can't take hairpins hot with them lol
