I am new to this forum and like to share with you an exhaust i just installed. i just installed the fujitsubo legalis r exhaust on my tsx and let me tell you guys this exhaust is by far the quietest i ever heard. Definately quieter then the greddy sp exhaust. The intake is alot louder then the exhaust. If any one plannin on purchasing an exhaust definately go for this one you wont be disappointed.
