Which muffler to buy
« on: August 14, 2018, 09:04:00 PM »
I have a cb750 K7, I have a 4 to 1 exhaust and I am looking to buy a reasonably priced muffler. I am just looking for something simple that is not too loud or too quiet. Preferably short. Any recommendations would be greatly appreciated.

Cone engineering makes very high quality kit. Here's their 18" Quiet Core on my Delkevic 4-1:
