So I just recently replaced my single in dual out Flowmaster 40 series with 2.5" tail pipes to one glasspack with a 2.5" tailpipe and it seems to be quieter than my 40 series. The main goal for this was I wanted my truck to be loud and aggressive, But now it is the total opposite of what I had planed. Any ideas why it got quiter instead of louder? Anything I can do to make it louder? And does anyone have a hollowed cat with a glasspack because I want to know if it is too loud..
