Nah I wouldn't touch the hks well thats just me, I was very picky when it came to choosing an exhaust. the js racing one and toda look alike but they were just too loud for my likings. then there was the fujitsubo and mugen twinloop both were quiet exhausts, bought the rm because jdmyard was doing a sale last year. if you like some noise on crossover and a quiet tone best to go with mugen or fujitsubo.
