Just noticed on SLP`s website updated info the 2009 pipe`s for the d8`s, they say no EGT resistor. For 2008 d8`s they say to install the resistor. Question, does the resistor need to be used with the 09 piston/head/ecu reflash on an 08 d8. Maybe somebody knows the answer? Otherwise will have to email SLP in the new year after I get back from holidays. Will be installing my pipe then. Merry Christmas to everybody.
