Pro Circuit TM 125 13–On

The Pro Circuit is one high quality exhaust muffler from Pro Circuit, designed for motocross and off-road riders looking to replace or upgrade their motorcycle's factory exhaust. Designed to improve exhaust expansion and overall performance, this muffler offers more linear power flow, better engine response and more efficient operation compared to the standard factory final.

Construction in this category of Pro Circuit products typically includes lightweight 6061-T6 aluminum body or combination aluminum and stainless steel, with welding techniques that ensure resistance to high temperatures and harsh motocross conditions.

This type of muffler is ideal for riders who want to maintain or increase their engine's performance, while managing the vehicle's acoustic behavior in a more "restrained" and factory-friendly manner.
