dynomax vs. dynomax ...

Hmmmmm

I didn't think the Super Turbos were that quiet, at least
mine aren't.
they arent silent, but if i can hear my rad fan spinning when i rev it ... exhaust is too quiet ! i do appreciate to lack of noise on long trips, but doesnt happen often enough to worry about it ..

I run ultra flows on my car. Just a tad louder then super turbos but zero back pressure. Love em...
dude is that your car on youtube ? if it is that sounds awesome !! im getting the ultraflow polished s/s ..
