The mid rannge on the 11 and up Apex's is unreal. I have 13k miles on my 11, not a single problem. I just changed all the wheels and exhaust donuts prior to this season, not because I had too, just because it felt like it was time.I guess we will see...my 07 Attak was a rocket...I never lost to another apex with it...it would stomp my buddies 06 rtx...I keep hearing the mid range is stronger on the 2011 or newer apex's. ..I know for a fact my Attak would eat my 1000 cat..I can only hope this xtx will do the same
