Sounds good! I have Spintech on my truck also. Much nicer sound that Flowmasters.

What series mufflers are those?

The youtube comments say they're SPORTSMAN STREET 3000XL.

I also had Spintech 3000 series on my 402 BB. They were too loud and droned, for me.

Much happier with my dynomax super turbo mufflers, now.

I’m running Thrush turbos, and I like the way they sound, but the rest of my system is stainless and I want stainless mufflers. I thought about the Dynomax super turbos. I like the way your truck sounds too.

I also like a more quiet ride and put these on my bone stock 402BB and am very happy. Not a lot of mileage on them though.

Folks - these are quiet in the cab but great sounding outside...

The Thrush turbos are pretty quiet until you get on it then it gets loud. But not as loud as with the electric cutouts opened up…:metal::metal::metal:

Dynomax super turbo mufflers for reference: https://youtu.be/O39GYbJp5jM?si=-EtkcIbU26k7tpMk&t=128
No drone, vs the Spintech 3000's I had.
