Why Doublewall?
Guaranteed Not To Blue.

True Doublewall construction was created to eliminate bluing — a pipe within a pipe! Because of the way they're designed and made, this unique feature keeps every Hard-Krome pipe looking beautiful from Day One.

Every Hard-Krome pipe is designed to not only fit great on your bike, but look great too. Extra steps are taken in the manufacturing process of our True Doublewall design to make sure that fit and finish is perfect. We don’t make any compromises in the way we build our pipes, because you don’t make any compromises.

But we’re more than just another pretty pipe. Hard-Krome pipes really perform! The midrange performance on your bike suddenly picks up so you can smoke everybody else. Only Hard-Krome pipes perform as good as they look!

Hard-Krome pipes are the biggest in the world! We believe that bigger is best when it comes to making pipes, and they make any bike look better. When you bolt on a set of Hard-Krome 2.5-inch to 3-inch diameter pipes, nothing else measures up!

Hard-Krome pipes sound the best too! It’s a solid, gutsy tone that's different from the competition. One twist of the throttle and everybody knows you’re running Hard-Krome!

RES-TECH Drags. New for 2007! RES-TECH exhaust systems feature large 3" diameter mufflers constructed with Hard-Krome's RES-TECH (Reduced Exhaust Sound TECHnology) patent pending. Using RES-TECH muffler cartridges to reduce exhaust sound to an acceptable level, they maintain good aftermarket performance. RES-TECH are our lowest sound exhaust systems.

Our mission was to invent a muffler system that had the lowest sound yet retained the highest power in every measurable facet of performance. The end result of our work had to be clearly observable as better than any muffler system used in the past, by motorcycle riders around the world. Our R&D team genuinely exceeded our goals. We honestly feel that this is the best muffler system on the market today.

What is a RES-TECH cartridge? First, we use the largest diameter muffler body on the market. Next, we use the absolutely longest muffler possible. However using a large volume muffler is only the first step. The RES-TECH cartridge is about 3 times longer than most contemporary mufflers.

We then thoroughly tested all of the louvered baffle and perforated core designs available. We went with the lowest sound/ highest power ratio combination that we could find. Then we use, multiple layers of several sound absorbing materials, tightly wrapped around the RES-TECH core and compressed into a lightweight extremely thin wall tube. Finally we seal the unit together. This is the "cartridge".

In the past, you compromised either sound or performance. Now with Hard Krome RES-TECH muffler systems you can have the best of both worlds. Only RES-TECH (Reduced Exhaust Sound TECHnology) cartridges will enable you to have a high performance / reduced sound exhaust system.

The New Boost Port
Hard Krome has developed a new cross-over port system called the Boost Port. This cross-over port connects the two dual exhaust pipes together. Click to expand.

Hard Krome has developed a new cross-over port system called the BOOST PORT. This cross-over port connects the two dual exhaust pipes together. This increases power significantly due to the benefits of improved exhaust scavenging and charging. You experience the same power gain that you would get from a 2-1 exhaust pipe, but with the good looks of a dual exhaust system.

Hard Krome pipes with Boost Ports are available on some M109R, Roadliner and Stratoliner pipes. Look for the Boost Port logo.
