DSE engine mount/header question

[JMitch19]

I have them on my car and they fit. I laid them side by side with a DSE header. They are nearly identical. There were a couple of bends on the DSE header that weren't as tight and may flow marginally better. Quality wise they are a nice part. I sold my DSE headers only after making sure the Holley fit.

Another benefit is that the collector is straight and doesn't have the angled Vband that DSE uses. I have the Holley blackheard header back exhaust that is designed to work with the quadra link. Everything fit with no cutting. The only cuts I made to the entire system were on the tailpipes so they didn't stick out below the rear valance.
