A damn good price. And I really like the sound of the DynoMax. Grumbly- not obnoxious.

I bought a dozen back when Holley was selling NOS ones for $10 each with free shipping I sold them all for $60 a pair. still a good deal on these considering Summit price is $53

How do these mufflers compare to the mufflers that came with the Jegs 2.5" dual exhaust kit they had on sale a while back. I think this is a link to the kit.

They are probably similar, just in 2 1/4.

This is a good economy muffler to have around. It can be used in a variety of applications. I will be using a set on my 1978 c10 and on a test stand to break in a engine before installing it in the car.

I still have the Jegs kit I bought back when it was on sale, the Dynomax are a turbo muffler while the Jegs muffler design is more like the Dynomax ultra flo with a wrapped perforated tube, I am not sure what the sound difference will be.
