Two Brothers Exhaust Reviews

two brothers racingTwo Brothers Racing exhaust systems are famous for being lightweight and loud (but according to some reviewers, not too loud). Each aftermarket exhaust includes a spiral-wound perforated core and comes in a variety of can materials including carbon fiber, aluminum or titanium.

If the phase “Made in the USA” means anything to you, you’ll be happy to know that Two Brothers exhausts are handmade in their Santa Ana, California workshop.

Company Background

Craig Erion and his brother were the founding members of Two Brothers Racing over 30 years ago. They started racing Honda motorcycles in 1985 and were passionate about finding ways to increase the performance of their bikes.

After years of testing and tweaking, they developed a motorcycle exhaust that was turning heads at the track. In 1993 Craig decided to step away from racing and build their proprietary performance parts full-time.

Today, Two Brothers Racing exhaust systems are still handmade in their Santa Ana, California shop. Better yet, they still deliver the same great horsepower and sound that made them popular in the early ’90’s.

Construction Quality

When shopping for an aftermarket motorcycle exhaust it can be hard to tell which brands are high-quality and which are just over-priced. Well, if you’re on the fence about forking over $400 for a Two Brothers exhaust, I have some good news.

A new slip-on exhaust from Two Brothers Racing will give you instant horsepower and torque gains as well as significant weight savings over stock.

Although you can buy one of their exhausts in a wide range of styles including aluminum and titanium cans, their most popular model has to be carbon fiber. They are constructed from military grade custom carbon fiber and the aluminum inlet and outlets are CNC machined for a perfect fit.

Most of the exhausts they sell include V.A.L.E. (Variable Axis Locking Exhaust) attachments for easy installation. This is a patent-pending design that allows you to install your new exhaust without welding or springs.

Although it sounds high-tech and potentially complicated, V.A.L.E is just a simple clamp that will make your life a lot easier. It will help hold your new muffler in place while you make your final adjustments.

Common Complaints

After you install a Two Brothers Racing exhaust on your motorcycle I don’t think you’ll have any complaints. How do I know this?

Because I had a hard time finding negative reviews of their exhausts after reading hundreds of comments from customers all over the internet.

That’s because you get what you pay for when purchasing a premium exhaust system. Most customers were very happy with the new sound they got out of their motorcycles. A Two Brothers exhaust sounds great but it’s not too loud.

Also many customers were impressed with how easy and fast the installation was. That’s likely due to their V.A.L.E attachment and CNC machined inlets.

If this is your first aftermarket exhaust, there are a few things to keep in mind. Of the few complaints I did find revolved around the exhaust drone you’ll experience at cruising speeds.

As with all straight-through mufflers, whether on cars or motorcycles, you’ll be rewarded with great sound but you’ll have to put up with a high pitched drone at mid-range RPMs. I guess it’s a small price to pay for better horsepower and high-end torque.

Another thing to keep in mind is that motorcycle exhausts need to be repacked to maintain their great sound. While this can be frustrating, Two Brothers makes it very easy to repack and replace all parts of their exhaust systems.


If you want a race-proven exhaust system, nobody has a performance-backed resume like Two Brothers Racing.

Their most popular carbon fiber Black Series exhausts can be found on the street and even at the track. Of course, it’s no surprise since they deliver a high-performance exhaust at a reasonable price that even a small budget rider can afford.

Although it’s becoming less common these days, Two Brothers still manufactures their products in the United States. Every exhaust is carefully handmade in Santa Ana, California so you know you will get a high-quality product that was carefully inspected before it was shipped to your door.
