Flowmasters

Sound depends on the motor.

I had a relatively mild 351 in my 69 with some kind of turbo mufflers on there. After I built my 393 with aluminum heads, aggressive cam, etc, I hooked up the same exhaust system and it is twice as loud. Compression and cam profile and displacement make a huge difference in sound.

Anybody who says 40 series flows aren't loud probably has a fairly mild motor.

true, i had a worn out 302 that i swapped for my roller 5.0 recently. When we first started it, my mom leaned over and yelled in my ear "why is this thing so loud now?" im pretty sure exhaust noise doubled changing motors.

I want to change to LOUD exhaust. whats the loundest out there???? (and for all you old geezers who are anti-loud, it is cheaper than a stereo)

well this is quite odd. i have the 40 series flowmasters. 2 chambers. And i don't really think they are loud at all. maybe the way my exhaust is set up might make it different. But when i'm at idle..parked, it's really a deep sound to it. and it's not loud at all. lol strange :-|
