Doug's Longtubes and Mufflex Y-pipe
Does anyone know if the Dougs Longtube headers and the Mufflex Y-pipe bolt together. I am considering getting Doug's over the Hooker 2210's.

yes, it willl work. that is my setup all though i modified it a bit more to get more ground clearence and also welded the exhaust vs the clamps because the kept getting loose very easily.

Brought back from the dead.
Just looking for any more input from those using the Mufflex y. Anyone else have experience with this and the Doug's headers? Opinions?
