I would like any input on performance, dyno info, associated with different mufflers. I have an altered 911 muffler, dual outlet. I would like to replace with 14" stainless mufflers that weigh 3lbs each. I could drop 20# of the rear. But I am afraid that the straight through muffler, will not produce enough, or as much back pressure as 911 type. Result in loosing some mid range torque. Is there anything that could off set this, short of internal changes, cam, etc.?
