I had Blowmaster 40's on my car and I hated them. Ricers looked at me funny. LOL But to each their own on sound.
Turbo's will give you a quiet sound with a minimal deep tone (I had them on a 78 Trans Am, 6.6 liter) and it was quiet to me, but my other car was my 70 Chevelle built with Flows
Borla, if set up right, will give you a nice deep mellow tone and have a good sound throughout the RPM range.
As silver said with the Maxflows, if I'm not mistaken they are In between turbos and borla's in loudness. He can comment on that.
Hell, just go get you some Purple Hornies,

The names sounds cool.. LMAO
