It bothers me a bit. In regular drive mode it is fine. In ds mode not bad either. When I put on the cat back with stock intake with k&n filters I had no hiss at all. Later the same day I put on the stillen g3 intake is when I heard the hiss the first time. RHFC made it a bit louder. I will get use to it. If you have a 6mt you can just put it into neutral when you are coming to stop.
Car sounds fantastic during acceleration. And you can not argue about the extra power

I actually love the hiss the RHFCs produce. I actually had someone ask if my car was TT'd on my G37 when I would speed up in 2nd and let off the gas. Was quite amusing.

I would buy it again, plus it has the approval of my 8 yr old granddaughter. picked her up from school.. she has me shut the car off and restart it while she is standing outside the car.. as soon as it starts she smiles and gives me the thumbs up!
