What is the noise you all are calling drone? Ready to fire up my 440 with TTI's with mild muffles,, need to know what I might expect.... Thanks



John, the "drone" is a small point in the RPM range, (2200 or 45MPH on my GTX with 3.23 gears) where the exhaust note gets so loud it's almost painful. I've been avoiding that speed quickly which is possible but I see some of the guys fixed it by putting resontors at the end of the tailpipes like the Hemi cars. I will try this soon.
