we installed the Synapse Hemholtz resonators on his 3" SZ system... marked the test pipes on the car for fitment and pulled them and took them to an exhaust shop for install... basic cut and weld operation that was fairly quick and cheap. I'll let him comment on the noise reduction, I just helped get them installed.
