pressure question with duals
pressure question with duals pretty much any gear except first, when rolling and I let off the gas after about a second or 2 of the regular gurgle gurgle, it seems as if the exhaust is creating some sort of vacuum. Then you tap the gas again and it seems to reverse the vacuum and POPS. Its been doing it since I've had the headers exhaust for a year with no adverse effects on power, just bugs me and I wonder if I'm gonna float a valve or something
