Re: BB 402 with Spintech Sports Mufflers

Have you had the opportunity to go on a decent length drive yet? If so, was there any drone or annoyances at prolonged highway speeds?

The longest trip was about a 200 mile round trip. Not that I noticed. It had the BB sound when I kicked it in but never noticed the drone affect.
