I had the Librands manifold fitted on my 4/4... the difference in performance before and after was very noticeable even without an ECU re-flash. That's coming shortly!
I believe LIbrands use 'Janspeed' to manufacture their product... it's a very nice quality exhaust with smooth welds in and out. And car had no issues getting through the MOT emissions test either with the accompanying 200 cell catalytic converter.
