Suzuki DRZ400e Muffler - 2002 to Current
The dual purpose DRZ400 summarises the perfect bike for the adventurer that enjoys simple trail riding and an open road. It is a strong foundation to build a great adventure bike that is light weight and reliable. While a solid adventurer, with only 400cc behind it, the lack of power was something we knew we needed to address with our design.
When designing the Sports Muffler for the Suzuki DRZ400 we focused on reducing dead weight in the suspension and also adding a decent exhaust note. The design of the sports muffler uses a 50mm stainless steel straight core to improve bottom torque and make the bike less restrictive. Our design resulted in a 4 horsepower gain over standard with a more responsive throttle and much lighter back end which completely changed the rideability of the DRZ.
The on road test of the DRZ400 fit with a Staintune Round Sports Race Muffler resulted in considerable gains from the bottom end and through the mid-range. The throttle response on the Suzuki DRZ400 is crisp, as you crack the throttle, you’ll get an instant response.
Overall, as a rider you will experience much nicer rideability with a deep exhaust note. Truly turning your quiet and reliable bike into something you want to show off to your mates.
