Hi yall, looking to put on a new exhaust on my 90 fleetwood brougham and unsure of what route to go. I have the 307 Olds motor and just want something that makes it sound throaty but not too loud, just a rumble, and possibly true duals. I have flowmaster 40 series on 2 of my other cars which are v6s and i like the sound, but i dont want to change the attitude of the caddy, just want to give it some rumble. any ideas would be greatly appreciated.

Dynomax have an "old school" sound to them, whereas Flowmasters tend to sound better on cars like F-bodies or Mustangs. Beautiful Brougham, by the way!

Thank you very much for the comments. I like flowmasters dont get me wrong, I have them on my 2 3.1 4door Luminas and love the sound, but i dont want that sound on a classic Cadillac. I might check into dynomax, any way if they have a sound preview or anything anywhere

I use flowmasters on my 57 chevy, they are in a 3" exhaust system behind a street-build 454. I love them in that application but find them a bit tinny for stock exhaust systems. IMO Dynomax Super Turbos seem to give the best overall tone when installed in a stock exhaust system behind the factory engine. Nice mellow rumble but no drone at speed.

If you go with duals, I would also suggest a crossover pipe as well, it will help to even out the exhaust pulses. For a stock caddie with the 307 you don't really need to worry about using an H or X pipe for a crossover, it won't make a difference.
