Pro Circuit Yamaha YZ250 YZ250X Works Pipe & R-304 Bundle — Champ Power — 0732525, SY03250-RE

Pro Circuit Performance Bundle — Matched Champ Power, Get The King of Supercross Setup

Stop guessing which exhaust combination works best. This Pro Circuit bundle pairs the legendary Champ Works Pipe with the R-304 Shorty Silencer to solve the "flat" power delivery common on stock setups. This high-performance package is based on the original pipe developed for Jeremy "The King" McGrath, offering a massive boost in horsepower and torque that you will feel across the entire RPM range.

The Champ Works Pipe is constructed from stamped AKDQ high-quality carbon steel with hand-welded and pounded seams for Factory Quality fitment and flow. Paired with the R-304 Silencer's 6061 T-6 brushed aluminum body and stainless steel intake tube, this system provides the ultimate "Works Look" while maximizing throttle response and over-rev for closed-course racing.

• Pro Circuit Champ Works Pipe (0732525): Unplated, oiled metal finish for authentic factory aesthetics and increased durability.
• Pro Circuit R-304 Shorty Silencer (SY03250-RE): Compact race-only design for optimum performance gains and lightning-fast throttle response.

• Instant horsepower and torque gains noticed throughout the entire RPM range.
• Hand-welded and pounded seams ensure precision exhaust gas velocity.
• Lightweight 6061 T-6 brushed aluminum canister reduces overall bike weight.
• Easy maintenance with hex head screws for quick silencer re-packing.
• Factory Quality reinforced mounting brackets and stinger for long-term durability.

Moto-House MX Pro Tip:

Because the Champ Works Pipe features a raw, unplated finish, it requires a little extra love to keep that "Works Look." We recommend applying a light coat of WD-40 or a similar penetrant after every wash while the pipe is still warm to prevent surface oxidation and keep the metal looking fresh.

FAQ Questions

Q) Does this bundle require jetting changes?
A) While designed to work with stock settings, we highly recommend checking your spark plug color. High-flow systems often benefit from a slightly richer main jet to maximize the performance gains.

Q) Is this silencer spark arrestor equipped?
A) No, the R-304 is a full-race "Shorty" silencer designed for closed-course competition and does not include a spark arrestor.
