Message	You can almost ALWAYS hear them spool with Greg's Downpipes... HOWEVER... if you've had them on your Z for a while, or do not have the opportunity to hear a Z with stock precats, you won't know what to listen for! Also, the tone of your exhaust plays a HUGE role in hearing them spool. If the exhaust is too deep and throaty, it will drown out the turbo spool. From my experience, you can hear a stock turbo spool with Greg Dupree DPs on a Z32. You can MOST DEFINITELY hear anything bigger than a Sport 500 spool on a Z. I've worked on 2 Zs with Sport 500s and Greg's DPs and you can DEFINITELY hear those babies whistle. Also as a word of note, I have a T28 on my 200sx ('84) with a Greg Dupree DP. You can hear that baby spool at only 7psi... ^_^ Can't wait to hear it at 18... ^_^ Later!
