i had a glasspack and i hated the sound...it was way too loud and had a drone to it that gave me headaches everytime i drove the tour...my opinion is to get what i have now, which is the magnaflow...its more $$$ but definitly worth it 100%....you will love the sound...it is deep but not ricey ....the sound is amazing....works for me
