Pro Circuit – R-304 Shorty Silencer

When you’re chasing every fraction of a second, the Pro Circuit R-304 Shorty Silencer delivers the edge you need. Designed purely for closed-course racing, this compact silencer gives your two-stroke lightning-fast throttle response, a sharper power hit, and that crisp factory tone every racer wants to hear. Lightweight, tough, and built for speed — it’s a race weapon through and through.

Constructed from 6061 T6 brushed aluminum with a 304 stainless steel intake tube and stainless steel end cap, the R-304 is engineered to handle the abuse of real competition without adding weight. The E-Glass internal packing lasts longer and keeps performance consistent, while allen-head screws make repacking quick and hassle-free. Every silencer is TIG and MIG welded by hand in the USA, ensuring strength, precision, and a perfect fit. A double-walled mounting bracket keeps it rock solid, and the short-can design gives you that instant, snappy throttle feel that wins races.

Why We Like It:
It’s the silencer that makes your bike feel like a true race machine. The R-304 hits hard, sounds crisp, and helps the motor rev quicker — perfect for aggressive riders who want instant response and clean, predictable power.

Why It’ll Work for You:
This silencer helps your bike accelerate faster and respond immediately when you roll on the throttle. The shorter design focuses the power in the low-to-mid range, making it easier to pop out of corners and hit jumps with confidence. It’s lightweight, durable, and easy to maintain — everything you need for consistent performance and race-level results.

Variants / Options:
Available for a wide range of two-stroke models. Designed for closed-course racing use only.

Worked for 2024 Honda CR-V Sport (Hybrid). Sizing was appropriate and the new filter slid in without any issue. Consider the filter to be of good quality. Would recommend.

Great product
Size: 9.3" x 9.7" x 1.8"
I recently installed the BOSCH 6029C HEPA Cabin Air Filter, and the difference was noticeable right away. The air inside my car feels much cleaner and fresher, especially when driving in traffic or through areas with a lot of dust and pollution. It does a great job filtering out odors, pollen, and even fine particles—I’ve had fewer allergy issues since switching to this filter. Installation was straightforward and only took a few minutes, even without much mechanical experience. The build quality is solid, and it fits perfectly without any gaps or issues. Compared to standard cabin filters, this HEPA version is definitely a step up in terms of filtration performance. Overall, I’d highly recommend this to anyone looking to improve their in-car air quality. It’s a small upgrade that makes a big difference in comfort, especially for daily drivers or people sensitive to allergens.
