How do the Magnaflow mufflers comare in noise level both inside and out to Flowmaster or Dynomax bullets. I've tried to find sound clips on You Tube and what not of the Turbo XL Mufflers, the race series, and the regular stainless series. I've seen posts on here that magnaflow's are really good about not having much drone inside the cab. Does that include the race series bullets?? And does anybody know how the Turbo XL, or Turbo XL SS series mufflers sound ??? I found 2 of the Turbo XL SS mufflers on ebay for $90 shipped. ($65 + $15 shipping). Those would work perfect on my x-pipe set up if they sound good. Any input ??
