#17 of 19 2007 SONATA V6 FLOWMASTER MUFFLERS by tgrose Oct 30, 2009 (8:54 am)
I installed a pair of 40 series 2 chambers. They sound very good - no bumble bee sound, but my highway gas mileage dropped from 32 to 26. I guess it's a mistake to cut off the factory mufflers and sacrifice that many MPG's. My mileage to and from work has not changed??

Replying to: tgrose (Oct 30, 2009 8:54 am) If your new mufflers restrict the flow any at all it will drop your HP and MPG. It happened to me before. With catylitic converters the system may be thrown off. Just the opposite happens if you open the flow you will gain HP and MPG like when headers are installed, have done that also. I used to work on my own vehicles but with all the new junk they have on them it takes a computer now.
