Flowmaster Delta 40 Series vs. Thrush Welded Mufflers (1968 Pontiac 400)

On this video we install some very close mufflers on the car. I have not found 1 comparison between these 2 mufflers. 2.25 in exhaust engine back, true dual tailpipes
Flowmaster Delta 40 Series
The extra delta plates inside reverb the sound a bit more, and don't allow it to get as deep as the Super 44 and the original 40 series. They also have more of a tiny sound than other Flowmasters and the welded. Good mufflers overall but just not my style. The drone is still considerably there

Thrush Welded
These have a completely different interior design. They are still a chambered muffler, but ive gained a few decibels in noise and even with that the drone is not as bad. still there but better than the Flowmasters. I am very happy with these as they have a little less drone even with the 40 delta series being advertised as a quieter loud muffler. The sound is also deeper and you can feel it more. And at the cost they are I definitely recommend if your looking for the deep sound of chambered mufflers and your more on a budget.
