This model of Muffler design came from Honda MUGEN "Twin loop" design.
The purpose of this design is to gain a little power but yet remain a little silent!
since the one you have is only a 尾鼓. it will fit any car, but it may not give you any HP gain. if you want HP gain, you need to get at least a Cat-back exhaust ( 中至尾) and or headers (exhaust manifold, 蕉)
