why does my exhaust change tones?

[redridder4]

I got a vibrant exhaust for christmas and every time i get to 4,500 rpm it changes to a different sound. Is this my 2nd exhaust valve opening?

Oh man.

Is there not an official "This is how the Honda VTEC system works" thread around?

Quick search netted this, im sure there are other resources out there. http://www.hondahookup.com/info/vtec.php

in a LS motor around 4000 the motor A/F mixes differently causing for a deeper tone.

in a GSR or a car equiped with a GSR Vtec is at 4300.

I used to love my old Non-Vtec Exhaust. DC Sport Axle Back. I don't know if they make it anymore.

It was quiet when it needed to be and deep when I sped up quick.

mines opens up(secondaries) @5500-8300rpm

the vtak in ur exhaust is causing the vtak in your engine to react differently and thus the vtak is making a different noise DUH!!! :roll:
