banks minster exhaust question

[757kevin]

i have a 4 in banks monster exhaust on my 99 250 7.3. i was told today that if i run the muffler backwards it will flow better. any truth to this. i was told that it wont effect back pressure or anything else. just wondering if there was any truth to this? dosent sound like it will work to me but yall are the experts here.

I've heard similar claims. The "straight through" type mufflers don't have much restriction at all. It may be slightly louder backwards, but not much. Even with a straight pipe, it isn't much, if any louder in the cab when just driving around. Windows down, it's noticeable. Outside the truck is another story.
