Installed on Subaru Legacy Wagon 5 speed 2003. I removed the stock muffler and installed this, a custom setup. The car also has a Borla manifold. The sound is excellent, but not much quieter than without the silencer, which surprised me. Very deep rumble and sounds good across the range. It dampens some of the harsher elements but doesn't calm the car down very much and brings some resonance to the cabin. I like the looks, the sound etc. but I wish the car was quieter.
