I own a 2001 R/T and found it has a California emissions Y-pipe on it's 5.9. Yes it has four oxy sensors. Besides the OEM, Does anyone know a place that sells a compatable replacement for less than (qouted from my local dealer) $1800.00 ? 1600.00 for the pipe assy and 200. for the core charge. What you think ?

 

The R/T has a 5.9, right? Is it a Dakota or Durango? In any case, the Dakota front Y pipe can be had for about $300 or so, http://www.rockauto.com/catalog/rafr...&parttype=5808

Id go with the rock auto y pipe, but, you might have to weld on a few more o2 sensor bungs because you have 4 of them..
