So as what I understand it remain 2 options (even if a 3L in the future)
The True Dual from SteBro (confirmed mandrel bent), 2 x 2.0'', no cats at 695$ (GB not sure to start, only 2 interested) But no dyno proven efficiency
OR
The Quasi-Dual from Brullen, the ''quiet'' one; (if I plan to gut my precats or get MSDS and install straight pipe in place of the main cat). at 510$ (or the yo-dude quasi at 490 but really really too loud for me)
---------
what could be the best setup between:
stock headers, stock y, no main cats, brullen/yo-dude Quasi dual
AND
stock headers, True Dual (no cats)
thanks
