Is there a difference in sound when comparing either two?

A. Flowmaster 40 series Single 3" center inlet/center outlet

OR

B. Flowmaster 40 series. Single 3" offset inlet/Center outlet

The basic difference in design is just the inlet. One is center, the other is an offset desin. Which has a more aggressive sound.

 

The Super 44 is the loudest street legal wise. The Delta Force 40 series is supposed to be the loudest 40 series. According to flowmaster. The 3 inch center inlet and outlet will flow better than the offset one. Flowmaster mufflers don't really flow well, but they have great sound. I've heard that the Mac mufflers have a similar sound but flow better than flowmaster. Go to youtube and listen to the flowmaster and mac mufflers and compare the difference.You can compare the spintech mufflers also.
