thse new hemis are NASTY LOUD straight piped. i took my muffler and tailpipes off to test it out. startup is very deep & rumbly. WOT in 1st & 2nd was insane. rest of the gears were pretty decent. not overly too much interior resonance for dumping under back seat. then swapped in my dynomax bullets (2 12" "race")--very deep and nice tone. much more mellow compared to straight. during my 2 test drives (about 6 miles total), i used 30 miles worth of gas, according to the EVIC.
