i found one from a website...
Tanabe Medalion Concept G Exhaust Honda Civic Coupe 06-UP P/N: T80115A
but i read the post saying it wouldnt be best for an r18...coz i got an LX and yeah im thinking of either getting this or a stock si exhaust..they almost sound the same but...i just wanna know what you guys think this would sound like on an r18
