Built 100% In-House in our Southern California State-Of-The-Art manufacturing facility the new 2014 Honda GROM 125 exhaust is a great blend of moto to street. We use our patented Factory 4.1RCT technology to achieve the best performance gains across the board. Massive 7lbs weight savings over stock and great power gains to match. The Factory 4.1RCT is available as a full system or slip on, using proprietary blends of alloy metals built 100% in the USA. Whether you are looking for that sleeker race look for your GROM or just want more power and grunt, we’ve got it!
