+1 on the no more DRONE..
I don't have aftermarket exhaust but have 4, 7/8 dia. holes at the back of the stock muffler. The sound is fine with me but the drone was horrible.
When I talked with Jimmy about the loops he wouldn't give me a yes or no on of they would clear up the drone. They did a huge improvement.

Thanks Jimmy for a great product..

For the chrome part. That's not how I received mine. They came bare metal then I painted them with VHT paint. That may have been an option I missed in the ordering process.
