I'm getting ready to purchase and s300 but the exhaust flange will not accept the factory turbo elbow therefore requiring me to use a 3rd gen hx40 downpipe. I was looking at Source Automotive's website and they offer a 4" exhaust flange for 2003 and newer trucks and I was wondering if this flange would eliminate the need for the hx40 downpipe and allow me to use the elbow ?

 

idk man, but u might try giving source automotive a call. im sure they will know since they are the makers. good luck
