Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Seems to be the difference between difillipo 3 inch and all other as well. Maybe it's all in the header design.HSV headers,they sound better than std logs but not as good as 4 into 1s,I had HSV headers,std cats,GTS mid section and bimodal cans,sound was loud and good I’d say very youthful,I then went 4 into 1,it sounds a lot better deeper I’d say mature.
