3.6 Muffler change...loss of HP and torque
I went from a 2 in and one out muffler to a two in and 2 out muffler.
The one out seems pretty constricted and basic. The 2 in and 2 out seems like it would flow better.
Problem is muffler change alone dropped the hP a full 5HP but worse yet 15# of torque.
Engine is a '95 3.6 with factory heat exchangers.
Would adapting a 2/2 out Monty work better? Any one done any testing on the dyno with mufflers for 3.6 transplants?
