Flowmasters don't flow well as other "straight flow thru" mufflers on the
market, but they're the loudest. Using it over a OE muffler will definantly
free up some horse power for you. I had the 40 series and they were
ANNOYING. too much cab rattle and very loud around 1700-2200 RPMS when you
give it gas and it doesn't upshift.
