In the world of exhausts there are a ton of options for the Harley-Davidson Twin Cam engine. One of them is the 2-into-1 “shorty” stainless steel pipe. These pipes are a fraction of the weight of stock H-D exhausts, they usually make good power, and sound good when either at idle or wide open throttle.
We have had a few stainless 2-into-1 pipes on our project Daily Dyna (2015 Dyna Low Rider) and we were fortunate to get a pipe from the folks at Royal-T Racing to install and test. Here is how it went together.

As you can see quality and attention to detail on the Royal-T Racing pipe is second to none. Every weld is near perfection and even the machined components are top-notch.

We start the installation of the Royal-T Racing pipe with the installation of the exhaust flanges.

This Royal-T Racing pipe came with the larger O2 bungs but the smaller ones can be ordered as well. We just used some adapters to make sure our sensors fit correctly.

Plenty of anti-seize compound was used on all threads.

Our pal Holden installed the front pipe onto the forward head of the engine.

The back O2 sensor was then installed on the rear section of the exhaust.

The rear section of the pipe was installed onto the rear cylinder of the engine.

The Royal-T Racing muffler mount is a very simple, yet effectible component.

The muffler mount simply attaches to the bottom of the clutch cover with the stock H-D Allen bolts.

Holden then slid the proprietarily designed Royal-T Racing muffler onto the head pipes.

Once all of the parts of the exhaust were aligned we snugged up the head pipes.

The Royal-T racing pipe uses a set of exhaust retention springs like many MotoGP and streetbike exhausts do.

After torqueing everything to factory specs we were all done. As you can see this is a short, no-nonsense kind of exhaust.

Here is how the Royal-T racing pipe looks on our project Daily Dyna. And yes it sounds as good as it looks. Look for the dyno number’s in next months “Tales From the Dyno” section of the magazine.
