So Im embarrassingly running a MAC 4 into 1 on my frame up resto project that will be finished this week. The pipe sounds nice but it looks like my 2 year old daughter did the welds with toothpaste. The quality is not the best, actually it sucks. I want to run something that sounds good, performs well, but looks great. What are you guys using? Does anyone have any experience using pipes from Benjie or similar? If anyone has an unused vintage 4 into 1 Yoshimura pipe from the 70s PM me...LoL
