My son is riding an 2004 rm125 mostly single track in the mountains and is looking to upgrade his exhaust. Fmf faty pipe and turbine core 2 look good ? Best suggestions. Thanks.

BEST ANSWER: Hello Dale, being a smaller engine and a younger rider the fatty pipe is a great choice. The Fatty broadens and smoothes out the power curve while boosting gains throughout the entire power band, more low-end, more mid, and increased over-rev. As for the TurbineCore 2, this is also a great choice. It offers unrestricted performance flow. The Turbunecore 2 can be used on the track or any trail thanks to its built in spark arrestor. This is a great set up for your son's RM125, the machine will gain a ton of power. Be sure to re-jet the carb and add a performance air filter and you'll be set. Please let us know if there is anything else we can do for you by contacting us by email at [email protected], Live Chat or by phone toll free at 1-888-339-3888.
