I'm looking for info and advice on an axle back upgrade for a 2010 GT. My only requirements are 4" dual wall tips and minimal or no drone. I've been looking at the MBRP and FRPP GTA as two of my top choices. Does anyone have the MBRP that can comment on drone levels? Lastly, I keep seeing different info on compatibility between years. Do the 2005-2009 axle back kits work on a 2010? I see some sites listing the same axle backs as compatible...yet I think I saw a different FRPP GTA exhaust (at 2 or 300 dollars more) listed specifically for the 2010 what's the difference? Some sites list the 2005+ FRPP GTA as compatible with the 2010...very confusing. Any info to clear this up is appreciated.
