I've wanted to try this exhaust hack for a long time...

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    • using SCIENCE to ELIMINATE exhaust drone: ...
