Installation requires cutting the OE system at the locations listed in the fitment notes. For 2008-2013 Toyota Highlander applications, the OE system must be cut 5-1/2" behind the rear converter weld. For 2007-2009 Lexus RX350 front applications, the OE system must be cut 5-1/2" behind the rear converter weld. For 2004-2007 Toyota Highlander applications, the OE system must be cut 3" behind the rear converter weld to fit with the OE converter, or 7-1/2" behind the rear converter weld for front applications. For 2004-2006 Lexus RX330 front applications, the OE system must be cut 3" behind the rear converter weld to fit with the OE converter. Verify the vehicle’s exhaust layout before beginning service.
