There is no noticeable difference when driving in a straight line at speeds of less than 40km/h.
You'll notice the difference when turning at an intersection or entering a tight curve at a faster speed than usual.
The car's behavior becomes clearly more controllable. Although it is expensive, I think it would be good to have it as standard equipment on the sports grade.

When shifting gears in a manual car, you gauge the timing by sound.
Therefore, sound is an important factor, and in my opinion, the Premier Tail Muffler certainly produces a deep bass sound that makes the engine feel more reliable when starting.
On the other hand, the sports induction box makes shifting more enjoyable as the high-pitched sound that rises from around 5000 rpm is very satisfying.
I recommend equipping two sets if possible.
