I put the RL exhaust on my car because I wanted a little bit more exhaust note and because I thought the car looked unbalanced with the single outlet. Something about the outline of an exhaust outlet on the other side of the car just looked "wrong".
I did not expect, and did not achieve, any additional performance.
I know that I prefer the look of twin exhaust outlets because I grew up in the era of V-8 muscle cars, when the dual exhaust became one of the features of a performance car. Is it useless ? Perhaps. But it is the look and sound that I like, and it was free.
I think it is a pretty arrogant reach for anyone to assume anyone else's motivations for doing something. Now, if I had put a V-8 logo on the rear fascia instead of the 2.4 ..........
