Smartpartz Hard Kore Quiet Baffles
For Your Hard Krome Exhaust
Story & Photos by Thunder Bob

There was a time when all you'd ever hear was, "how can I make my pipes sound as loud as possible?" I guess Dylan was right, the times they are a changin'.

It's not so much that some bikers actually want to go back to "stock quiet" as it is the search for a happy medium. Many driving factors have come into play that have lead to the unthinkable desire to reduce the sound on a set of aftermarket exhaust systems:

  • Some states, cities & municipalities have begun to clamp down on motorcycle sound levels
  • Increasing pressure from neighborhoods that have had their fill of late night or early morning "wake up calls" from straight pipes roaring off of a V-twin
  • Some bikers like their pipes loud, but would like them to be a little quieter
My company receives dozens of solicitations each month from prospective manufacturers and distributors, (the vast majority are off-shore BTW). So, when Chris with Smartpartz dropped in our shop some time ago, needless to say I was a bit skeptical.

Quiet Kore Baffles are made for Hard Krome 3" 2.75" & 2.5" exhausts only

He'd already installed a set of their Hard Kore Quiet baffles in Greg's Hard Krome pipes and Greg, an MT Staffer, was very happy with the results.

Chris offered to install a set of Hard Kores in one of our shop bikes, a 2004 Vulcan 2000 with Hard Krome 3" Big Straights. I figured, nothing ventured, nothing gained. The new baffles were literally installed in minutes without having to remove my existing HK baffles.

Once the baffles were installed, I took that big ole V2K out for a 30 minute, RPM rev limiter test ride! Man was I surprised with the results...quiet at idle, but they really wake up as you get on the throttle. The sound was deeper and throatier than before and performance was unchanged. Didn't have to make any adjustments to our Power Commander either.
