The Aluminum Tuned Pipe Set with Heavy Duty Steel Header for the Baja 5B delivers extra durability, more power and quicker throttle response than the stock muffler. The header is now made from large diameter steel tubing for extra strength. The exhaust flows smoothly from the steel header into an expansion pipe that directs the exhaust cleanly out the back of the buggy. The stinger design is optimized for a perfect fit in the Baja rear cage. The sound is louder than stock and tuned to sound like a 2-stroke motorcycle engine for realistic performance.

This set fits all HPI Baja vehicles and comes with everything you need, just bolt it on and feel the difference!

Reedy's 2035 and 2039 mufflers feature a 3-chamber design for a linear power band and exceptional all-around performance. A reinforced stinger and hard-anodized finish increase durability, while a single-piece pressure nipple is positioned for maximum body clearance and to lessen the chance of the pressure line being knocked off in crash.
