So I just had my Delta 50's installed and they sound almost identical to the Dynomax Super Turbos that were on the car before, I'm really confused. Do the Delta 50 series Flowmasters have a break in period, do they get louder the more you drive the car, or is the sound I'm currently hearing the end result? I also have a Roller Camshaft on the car, wondering if that might be preventing it from having the hot rod roar that I'm looking for. I'm still learning more and more about the car, so forgive me if I seem not quite as knowledgible as others on this site. Could the catalytic converter be quieting it down as well? Any advice would be appreciated.
