Horsepower Dyno Chart

More Power

Patriot® Defenders feature a step pipe design that promotes exhaust velocity while reducing reversion that can dilute the intake charge. By utilizing these technologies in conjunction with a formed merge collector and a state of the art perforated muffler core, Patriot's engineers have developed an exhaust system that performs on a par with other top brands for horsepower and torque while offering easy volume changes of the SFI valve and superior stainless steel construction. See the Patriot® Defender vs Thunderheader dyno charts here.

Loud When You Want... Quiet When You Need

With Patriot's patented Defender exhaust, featuring SFI* technology, just an easy adjustment takes your bike from DEEP RUMBLE to subtle quietness. Maybe you live in an area where law enforcement is cracking down on loud pipes. With the Defender you can ride at the sound you need. No discs to remove, no unbolting, no dirty mufflers to reach inside and turn - Just a simple adjustment.

Valve Action

Simple Volume Changes!

In the closed position, Defenders will generally replicate stock sound levels. As you open the SFI valve, sound levels and power output will increase with a deep throaty rumble that rivals any pipe on the market for great sound and significant power increases. To adjust the Defender's SFI valve; loosen the set screw on the SFI valve arm, rotate the valve to the desired sound level position, tighten the set screw - 30 seconds and you're done!

SFI stands for Sound Flow Inversion, Patriot's innovative exhaust baffle design that allows the rider to redirect the flow of the exhaust to instantly change the volume. In 1996 the first generation of SFI Slip On mufflers were produced for Harley's and quickly became a big seller. In 2005 engineering work began on incorporating the SFI Technology in to a performance exhaust system. That engineering effort culminated in the line of pipes now known as the Patriot® Defenders.

Patented Styling

The beautiful flowing style of the stainless steel Patriot® Defender is so unique; it was awarded a patent for its styling. Different from anything else on the market, this 2 into 1 performance pipe will also add to the good looks of your Harley Davidson® motorcycle. The pipes are available in highly polished stainless steel with chromed heat shields, black metallic ceramic heat coating with chromed heat shields, or black coated with black heat shields to suit any style of bike.

Round two
Back with part two of my review. Three months later after the install I took it for a test ride. Shazam!!! Throttle response and the "git up and go" factor is there when it wasn't before. One note, i would highly suggest that you purchase a tuner as well to map your bike. I bought one and mapped it myself and there is a noticeable difference. Minor note: If you like shiny things please be aware that these pipes are stainless and when heated, they get a golden hue. Does not bother me in the least. Go with the ceram coated pipes if this bothers you. If you think i am a shill for the company, think again and go visit Hammer Performance web site and see what the pros say. Can't wait to see what happens when I put the cams in in late Spring!

05 Softail install.
Product came a day earlier than expected and it was well packed with all of the components. Unpacking revealed a well made and solid system. Instructions were easy to understand. The installation was a bear and that is due to the moco's design. Be sure to go and purchase retaining clip spreaders as this makes the job of taking off the old clips and putting on new ones a breeze. I paid $14 but it was money well spent although it did not make the install go easier.

Once installed, I left the valve opened, and the map programmed, the sound of the pipes were impressive. I shed at least 25 pounds off of the bike by removing the true dual fishtails. Have not road tested them yet due to it being winter but looking forward to testing them out. They look a lot better, in my opinion, than the fishtails.

I did extensive research before I made the leap and am so glad I did!

Kudos for a slick product.
