well its def not the ART pipes that make the hiss on their own. was talking with kevin today, he just replaced his Gemini with the CNT racing exhaust and said he noticed the hiss and his gemini never had it. Hes had HFC for a while now.
So the ART pipes/test pipes probably make it noticeable due to the increased flow but its something that needs to be fixed in the exhaust. Hopefully the motordyne exhaust will do that.
