That's an interesting thought. The exhaust volume should go up with the engine rpm, but the raspy tone just can't be duplicated by reving the engine. However, it may sound similarly during higher rpm (5k+) driving.

its the car warming up so it revs at about 1200 for 10 seconds then drops to 1000 then 650 ish once its warm and the ECU has gone through its starting/warming protocols. now for the sound change that has baffled all of you is due to the metal of the exhaust being cold. once the metal heats up a bit is when it drops off. also the engine oil temp dictates some of that as well. not the oil itself but it's an indicator of the operation of the vehicle trust me i have straight pipes. so I hear every change that the Z's engine and functions go through. cold starts in mine are fuckin MEAN lol after it drops off though its a nice V8 like rumble. once the metal heats up the tone changes. then again once the car is up to full operating temps the exhaust note changes and gets smoother and better sounding then as well. you're all welcome :tiphat: |
^^^ Yep
Some of the ideas, theories and posts on this forum sometimes are a little...:icon14: |
Well it s nice to know you are reading the posts Whether they make sense or not.This is my first Performance car without a muscle V8 and its the first stock exhaust I ever heard that changes tone so quickly after a cold start up.
