Did you only weld one pipe or both? Pics would probably help.
I've noticed that Motordyne, ARK, and HKS all use Helmholtz resonators that look much smaller than 29" to cancel their drone. Seems like it works. Does anyone know why? And if resonators like that would work in drone reduction when welded onto any other exhaust? It looks much nicer than having long tubes imo.
