They all hiss on deceleration. If you hear air while accelerating you got a leak. Motordyne does make some badass products however its pricey. Unleash the VQs with LTH don't contain it. I'd rather have power vs dealing with a lil hissing noise. This car is not that fast being NA seriously IMO.

not sure what you are getting at. i didnt say anything about a noise during acceleration. try reading my post again....

You guys worry too much about the hiss and the rasp. It's part of the charm and character that the car has.

Read yours again then try reading mine again. Lol. It wasnt all about you bro. Just the part u said about..ark cats will minimize hiss on decel ONLY. I'm sorry I didn't know you we're suppose to hear the hiss any other way. The air leak was my insight. Along with why would u contain power just cause a silly noise. Sorry for the confusion.

I got the Z1 hfc on. I only hear the hiss when the engine is cold. Once its warmed up I don't hear it at all. I like the z1 hfc's, they add a nice growl.

What hissing means?? It is like a whistle or some??

My car has a horrendous rasp with FI test pipes, not at all a "hissing" noise.
From 2500rpm and up on accelleration, and then at about 4000rpm and down on decel. I think it sounds absolutely terrible and not classy.

Had to drive my Z to know wtf you all mean. No idea why you guys complain too much i like it tho.

With the windows up you can't hear it. And if the radio is on there is no way. Such a noticeable power increase for a little bit of noise on deceleration. Mine only hisses from about 2000-1500 rpm with the FI res. high flow cats.
