I installed this on
Subaru Impreza

Review
This twin plate really makes my driving very enjoyable. Smooth and quiet, very happy with it. When first installed not used to it as it feels different. As time goes by and getting used to it, that's where the fun starts. I personally like playing engine brakes so i believe you guys will know how noisy it can be but with this twin plate, you will feel the difference. Installed this for a few month already and really glad i did. Just a bit of what they call the seal call sound which is refered as for the sound i find from other review but does not really affect my driving so not much of a issue.

What I like
Smooth and quiet, makes my driving experience better

What I do not like
The so called seal call sound but pretty minor and does not affect driving so I can live with it
