Solo Mach X vs Mach XL
I know the only difference between the two systems are the J-pipes.
Does anyone here have the Mach X on an L99 with the AFM tuned out? I am trying to find out if there is any drone on the Mach X.
Asking the same question a slightly different way; does anyone have the Mach X on an LS3 and do they have any drone?
I am trying to find out if I should spend the extra $$ on the XL...
