Hard-Krome Exhaust - No More Blues. Guaranteed.
A Patented Design.
They said it couldn’t be done, We have 3 patents that say it could.In 1999 we invented the Double D (Doublewall Drag pipe) which was the first non-bluing pipe in over 100 years of motorcycling. This design was the first true “pipe in a pipe” design which we call True Doublewall Construction. The US Patent and trademark Office granted us several patents on our concept and designs. (US Patent #6,408,980, #6,648,099, #6,715,581 and other patents pending). Our patents insure you have a unique product for your individual style.
Guaranteed Not to blue for one year*
We are so confident that our pipes won’t blue that we offer the industry’s first and only 1-year guarantee* against bluing. We are in our 5th year of offering this guarantee.
