Never heard of that, but it sort of makes sense. If you just put the new exhaust on, then you are flowing air better. Hence, you're taking in more air now that your expelling more freely. Just to be sure, check your intake and make sure you have not had a separation anywhere, allowing unfiltered air in. If everything is fine and she runs well, I wouldn't worry about it.

My Intake sucks all the time. After i put on my exhaust, it just started. Theres no problem that i know of. I LOVE that sound!

My car does the same thing so I don't think its anything to worry about.

I was headed to the drag strip one night and a orange fox body stang pulled up next to me. I looked and said awesome car. This car was sweet! That thing was modded out the ***. He revved, and i revved back just playing around hoping we wouldnt race cuz he would kill me. The light turned and we both took off regular. I talked to him at the strip when we got there and he said he got scared when he heard that hiss. He thought it was a supercharger. HAHAHAHAHAHA
