this $150 junkyard muffler made my Silverado sound like a Corvette

I’ve built a lot of custom exhausts, but I've never seen anyone try this: a 4" Duramax diesel muffler on a gas truck. The gold standard exhaust note for a domestic V8 has to be a C6 or C7 corvette, and part of the reason they sound so nice is the factory chambered muffler, along with the equal length system. I can't do anything about the length on this portion of the build, but I do want to try a muffler that should get the sound in the same ballpark as GM's greatest sports car ever made. the twin turbos I am using for the 4x4 drag truck, the GTX3582r from Summit https://summitracing.pxf.io/bORqQx Tolman Performance merch https://www.tolmanperformance.com/ I made a quarter wave resonator to defeat exhaust drone https://youtu.be/l9CrmkIxDQU?si=yLE2707c3L6ELWBs
