Pro Circuit T-4 Exhaust System Kawasaki KLX 140

The Pro Circuit T-4 Exhaust System is designed to increase performance and provide more usable power throughout the entire RPM range. The stainless steel and aluminum construction offers increased strength and durability which is ideal for racing and most off-road riding conditions.

The T-4 muffler is also tunable, meaning you can remove the spark arrestor screen turning it into a race tip for closed course racing. The Pro Circuit RC-4 Resonance Chamber head pipe is included on select models and was designed to further reduce noise output by acting as a pre-muffler.

If you have been searching for a value priced complete exhaust system but are not willing to sacrifice performance, the Pro Circuit T-4 pipe is sure to fit the bill.
