Long story short I replaced the entire exhaust. I'm getting some resonance and/or slight vibration at a certain RPM and engine load. My original muffler didn't have the weight on it so I couldn't transfer it to the new one. Anyone have the part number for it?
Ive been playing with one of these mounted in different lacations. Currently mounted just in front of the muffler. Maybe my imagination, but its smoothed out a vibe/resonance I get at 2000-2400 rpm at hwy speed.
