69Mach1 M code 20 Report post Posted December 8, 2020 My 69 Mach has the original style dual exhaust with resonators and transverse muffler. I have never been a fan of the transverse muffler being positioned right next to the fuel tank due to tight packaging and being a heat source. Has anyone ever ran just the resonators or would this be similar to straight pipes and not a good choice for street use? If dual mufflers are the way to go, any recommendations?
