| VW Engines ...PF, RD, and PL use a double pipe in front of the cat at the manifold 16V engines use the double pipe. ARVIN Cat Numbers...ARV/29150 and ARV/29154 both use a double front pipe and should be interchangeable. BOSAL Catalytic converter # 099-910 | |

|
| PL 16V Engine same Cat different rear sections | ![]() |
| VW Engines... RV use a single pipe in front of the cat at the manifold This pipe uses a large single compression gasket with the funky spring clips ARVIN Cat Number ARV/ 29149 is used with the single front pipe...RV engines BOSAL catalytic Converter # number would be 099-906 | |
