Pro Circuit – 304 Factory Sound Silencer (KTM)

The Pro Circuit 304 Factory Sound Silencer is built for riders who want strong top-end power with a smoother, quieter tone. Designed for KTM two-strokes, the 304 uses a slightly longer body than the R-304 Shorty, giving you a broader powerband and reduced noise output — perfect for riders who want factory performance without drawing too much attention. It’s a race-quality silencer that looks clean, sounds refined, and keeps the power delivery crisp and responsive.

The 304 features a 6061 T6 brushed aluminum canister paired with a stainless steel inlet tube and end cap for lasting strength and a factory finish. Each silencer is TIG and MIG welded by hand in the USA, built to handle serious track and trail use. The double-walled mounting bracket keeps it solid under stress, while the allen-head screws make repacking simple so you can keep it running strong season after season.

Why We Like It:
It’s the perfect balance between power and refinement. You get that classic Pro Circuit hit, a clean tone, and a professional look that holds up to heavy use. It’s the silencer you can run anywhere — track, trails, or race weekend — and trust it’ll perform every time.

Why It’ll Work for You:
The longer canister design helps your KTM pull smoother through the mid and top end while keeping sound levels lower. It’s durable, easy to maintain, and built to deliver consistent performance without the extra noise. The brushed aluminum body and stainless end cap keep it looking sharp even after long rides and muddy days.

Variants / Options:
Fits most KTM two-stroke models. Compatible with stock or Pro Circuit pipes.

I have a 1999 Toyota Sienna LE
The starter was an almost an exact fit. The only difference was the rubber cover for the ground screw. The original started has a slight different design. Easy fix was the remove the old one and replaced it on the new starter. The fit was perfect. Used youtube video on starter replacement for my Sienna which was clear and east to follow. Took 2 hours to replace the starter. Waited a few weeks to see ensure the starter was working before I posted a review. The starter sound strong as the engine kicks over. Looks to be working fine. The dealers would have wanted $600 to replace the started. Some online poster says these Amazon knockoff are cheap and won't work. It started and time will tell how long it last. Its a 25 year old car. If I get another year or two use out of it, I'm good.

Almost a perfect fit for 2002 Avalon
The only difference from the old starter to this one is the old hardware had notches for the electrical connection and the old starter had a longer terminal post so I couldn’t swap the hardware successfully. Instead of returning it because I don’t want to walk to work again I decided to grind a notch on the new starter. Lucky for me it worked and I don’t show up with my uniform sweaty in a retail job anymore

Invonveniencia de reconstruir piezas como arranque, alternador.
Instalé este arranque en mi Camry 2002. Traerlo por Amazon a Caracas me costo la pieza y gastos de envío $112. Hace 8 meses se reconstruyó el arranque original con un costo de $180. Se dañó y decidí comprar uno en Amazon. Fue la mejor decisión.
