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.

Best Quality Socks & Great Thickness Plus Comfort
Size: Medium, Color: (001) Black / Black / Castlerock
I love these. They do not slip away from foot. The value for a good pack of socks was worth it. Has a good thick quality. They look clean and nice. Their stretch is good to get on and then molds to foot. Have noticed these socks have changed two times since buying. First they were slightly lighter color gray- then a darker gray but both had good quality and thickness. I am sure these are very durable but unfortunately I can not speak fully to this as the horrible steel toe shoes I have to wear rip everything apart. But if I had good shoes and everyday use of these I know they would stay good for so much longer than 6months.

Best socks ever
Size: Large, Color: (100) White / White / Mod Gray
Best athletic socks I’ve bought. I usually buy UA socks anyway and these are the best. Super soft and comfy. Fit snug and my feet don’t slide around in them.

Much much better than the standard sock
Size: X-Large, Color: (001) Black / Black / Castlerock
These socks are superb. Lots of padding in the right places, snug where it should be snug & loose where you don't want it to bind. They are marked with an 'L' for left foot, & 'R' for the right foot (it makes a difference in the fit being perfect. They stay up on your heel & don't slide down

4 lefts vs 2 rights
Size: Medium, Color: (001) Black / Black / Castlerock, Size: Medium, Color: (001) Black / Black / Castlerock
I ordered a set of three. I ended up with four left socks and two right socks lol. Granted it doesn’t matter unless you’re OCD. JEEZ. Love the socks but not the attention to detail the sock company did on matching left/right marked socks.
