If you're looking to give your Honda CRF 450R a little extra oomph, the Big Gun TFI Power Box is definitely worth a look. This isn't just another bolt-on; it's a solid upgrade that really makes a difference in how your bike performs. Designed for the 2009-2018 models, this power box is all about enhancing your ride without complicating things.
First off, let’s talk about what it does. You’ll notice an increase in horsepower and a snappier throttle response right off the bat. That’s thanks to some nifty third-generation technology that doesn’t require you to mess around with your bike’s computer. It’s a plug-and-play setup, so you can install it in just a few minutes and hit the trails without any hassle.
The built-in faceplate buttons are a nice touch, making it easy to tweak settings on the fly without diving into complicated menus. If you’ve got an aftermarket exhaust, this little gem is highly recommended. It plays nicely with your existing EFI setup, ensuring you get the most out of your mods without messing with the stock ECU map.
One thing to keep in mind: this product isn’t ARB/CARB compliant, so if you’re in California, you’ll have to look elsewhere. But for those in other states, you’re in for a treat. Plus, it comes with a one-year limited warranty, so you can ride with peace of mind.
In short, if you own a Honda CRF 450R from 2009 to 2018 and want to amp up your ride, the Big Gun TFI Power Box is a solid choice. It’s straightforward, effective, and designed with the rider in mind.

Big Gun Exhaust was founded in 1997 by former professional motocross racer, Mike Young, Jr., a three-time winner of the AMA National Four-Stroke Championship. He knew what it took to win the races and used that knowledge to start a business of manufacturing high-performance, quality exhausts for the motocross and sport ATV market, and eventually the side-by-side and street markets as well.
New Ownership, New SuccessAfter more than a decade of success under Young, Big Gun Exhaust was sold to a new owner in the hopes of facilitating further growth. In 2010, the company changed ownership once more, which called for tremendous restructuring in an effort to improve the brand. The new management and sales team helped rebuild the Big Gun Exhaust brand and streamline production and manufacturing processes under one roof in Corona, California. The more efficient manufacturing process resulted in a new level of success never before seen with Big Gun. Today, Big Gun Exhaust boasts one of the largest four-stroke exhaust product lines available and caters to the MX, Sport ATV, Utility ATV, Side-by-Side, Street, and Scooter markets.
