i'm getting ready to buy the 250DW-V6-Y and i've decided to go with a Flowmaster 44. I understand i need the offset/offset but what size for the inlet and outlet? Will the unions need to be welded or clamped???
Thanx in advance
Offset/offset. The 2.7L front is 2 1/2" and the rear is 2 1/4". You can buy either size since it has to be welded on anyways.
