Re: Check this (Crossfire Custom Exhaust)
It was my own design and I had the local mufler shop fabricate it. The muffler is a gypsy (offbrand). Total cost: $180.00.
Since then, I've added 2 small resonators and a crossover pipe in an effort to reduce the drone at 2500-3000 RPM. Sadly, it persists. I've learned to live with it.
I usually set my cruise at 78 mph and, at that speed, the drone is miniml.
