Rinehart Racing® Mufflers & End Caps

Rinehart Racing® Performance Parts

In the early 90’s Rinehart started in a basement garage one night using borrowed tools to fabricate exhaust collectors fora NASCAR driven by Dave Marcis. This led to the creation on performance parts that revolutionized stock car racing and then V-Twin motorcycles.

Today Rinehart Racing® is the largest V-Twin Exhaust brand making all of their parts in America for Harley-Davidson® & Indian Motorcycles®

Based in Asheville, North Carolina, they have become known Worldwide for creating great pipes with an iconic sound. That deep throaty rumble with the crisp high note is easily recognizable. It’s the sound V-Twin riders expect to hear when they start their engine.

While the sound is a major key to Rinehart’s success they also focus on bringing out the best performance from your engine.

We recently ran some Dyno tests using the same bike and some setup to ensure the results would be a fair comparison. We were curious to see how much performance difference a slip-on exhaust could truly make.

We ran the stock exhaust first to use as a baseline for comparison.

The Rinehart 4″ Muffler showed +2.23% HP and +9.76% Torque over stock. A nice result for a slip on with a great note.

This would improve even more with a high flow air filter & a fuel tuner.

We have seen great results with Rinehart mufflers on all size engines builds. (see Dyno chart below)

We have run Rinehart mufflers combined with Rinehart Headers in a Milwaukee-Eight Road Glide with a 128ci Cylinder Kit & an S&S 475 Cam (2019 114ci FLTRXS)

Awesome results!

Power: 76.7 -> 117.3 (40.6 HP increase / 52.9% increase)

Torque: 107.9 -> 137.6 (29.7 ft-lbs TQ increase / 27.5% increase)

Don’t shortcut your build, you never know when you want more power. Be confident that Rinehart have you covered!
