Install a Barkers Full Single Inframe Exhaust system on your Suzuki LTR 450 and you will hear and feel a difference. Feel your machine come to life with increased horsepower and torque throughout the entire power curve as well as eliminate that sudden fall of that most stock systems experience near redline. Installing a Barker's Full Single Inframe Exhaust System on your Suzuki LTR 450 is the easiest, most cost-effective way to achieve more horsepower and increased performance. 

For serious riding, we recommend purchasing a fuel controller for your new system. As your new system will require the added fuel flow, a fuel controller is essential for your LTR 450 to perform it’s best. For optimal results, your dealer or a skilled technician should program the fuel controller prior to installation. You might also consider purchasing one of our Big 3 packages that install with no additional modifications to your machine. Barkers offers 2 different Big 3 packages for the LTR 450 that will help you achieve even more horsepower, almost 26% over than stock to be specific!

Each and every Barker's Exhaust System is manufactured from premium materials that are hand welded right here in the USA. When most other after exhaust systems are mass produced robotically, Barker's Systems must be skillfully hand welded one-by-one. The exhaust pipe portion of your new system is made from 304 stainless steel that is Tig-welded with seam-reduced surfaces for smooth flow. The can is comprised of 6061-grade aircraft aluminum and comes standard in a brushed aluminum finish. You may also choose to have your can tips powder-coated in a black, blue, red or white finish for added character. Finish off your new system by selecting which color Barker's Tag you would like. You can choose black, blue, red or yellow.

At Barker's, we have an extreme amount of dedication and respect for the off-road lifestyle. And we understand that owning and maintaining a performance vehicle is no joke. That is why you can expect only the best in Barker's craftsmanship and design. All Barker’s exhaust systems carry a limited one-year warranty against defects in workmanship and/or materials. See Barker's Terms & Conditions.


Other options one should consider include the Barker's Quiet Core Insert and Spark Arrestor. The Barker's Quiet Core Insert is ideal when riding in those sound sensitive areas and can reduce sound by up to 5 dB. With only a loss of .5 to 1.5 horsepower, you may decide to ride with it in all of the time. The Barker's Spark Arrestor will prevent flammable debris from being distributed from your exhaust and will help keep our trails safe!


We recommend that you monitor and check the packing in your muffler after every ride. The length and time your packing will last will vary depending on how and where you ride. When you first notice any sign of the packing depleting within the can, it's time for a repack. Packing will wear out slowly over time, starting at 100% packed. It is normal for an absorption style high-performance muffler to lose packing but once you lose more than about 10-15% of your packing it will deplete faster and faster since it can now move around in the can. It is imperative you do not allow the packing to deplete too far. If your muffler becomes very loud or you hear rattling around inside the can you have completely depleted the internal packing and should not ride the machine until the muffler is repacked with a fresh pillow. Order new packing before you need it!

The Barker's Exhaust Complete Repack Kit is designed to make repacking your Barker's Exhaust Can simple. *NOTE: If you have a dual system you will need to purchase 2 repack kits.
