I have the Super Turbo's on my Valiant, I like them.

My girlfriend said they made the car "echo" too much inside.

I added some sound deadner material to the floor under the rear seat,
because there was No padding/carpet etc. under the rear seat. :(

I also added some carpet padding to the trunk divider,and under the rear seat.

Now the car has lost the annoying resonance inside, but still has a nice sound.

You can sort of see the padding behind the trunk divider cardboard,
I used 3m spray glue to attach it.
