Here's the benefits of installing Smartpartz Hard Kore Quiet Baffles ...
Want a quieter exhaust ?
It shouldn't be a big chore to have a quieter exhaust.
With Smartpartz quiet baffles taking a few decibels off your Harley or Metric Cruiser exhaust sound isn't difficult.
With our quiet baffles you will easily turn an obnoxiously loud pipe into a pleasant rumble that people can appreciate.
They'll still hear you coming, but they'll hear what your motor really sounds like, rather than having their ears assaulted.


"Successfully installed and noise level, at idle after idle warm up, has been reduced from around 90db down to around 81db.  I don't have a db number whilst riding, but the top end harshness has been replaced by a more mellow rumble and thankfully my ears may just have avoided long term damage - ie not ringing after only a short ride, and, as an added bonus I think the  neighbours' cat has returned home too :)  My sincere thanks for outstanding customer service and a product that delivers what it claims.  Good health and safe riding to all."

"Upon starting up the bike, I noticed an immediate noise reduction. It definitely took off the edge. While accelerating, the bike was loud, but not nearly as bad as it was, and a much deeper tone. While under steady load and speed, there was a pleasant 800cc rumble, but no annoying din of noise assault. In addition, the increase in the exhaust back pressure has eliminated the downshift popping that I had been getting.  Idling at a light is a pleasant change as well. I can actually hear myself think! I used a decibel meter android phone app before and after the install. At idle there was a 10 decibel drop in annoyance. The best part of all this is that my wife has stopped complaining about my bikes exhaust noise, and says it sounds nice!  Thank you Smartpartz!"

"Mounted the baffles in no time.  They look great and sound really nice.  I am pleased with them and I am sure my neighbours also!
Great stuff.

"Well, I installed the baffles. The roar of my pipes has been reduced noticeably. And you were right...they did tidy up the noise on deceleration.  Just as you advertise, they took the edge off ....... I've been riding with the Hard Core Quiet Baffles for about a month and love them! Overall, the volume is just enough quieter than before. The sound is a nice deep rumble when accelerating, but considerably more mellow when cruising at a steady speed -- just what I wanted. Performance hasn't suffered a bit and I'm getting the advertised MPG. Thanks guys!"
