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.

Good Suit
Size: X-Small, Color: Black
This suit is pretty nice. The fabric isn't extremely thin and cheap-feeling, and it fits really well. The shipping was really fast too. My son is 5'9" and weighs about 150 lbs. We ordered a medium first, but it was too big, so we returned it and ordered an extra small. The extra small fits perfectly.

It's a fun/unusual color, but not "celery"
Size: Medium, Color: Celery Green, Size: Medium, Color: Celery Green
Can't comment on the fit because we didn't take it out of the bag. I gave it 4 stars because 𝙦𝙪𝙖𝙡𝙞𝙩𝙮 of the suit looks really nice through the plackaging, but we didn't open it up and try it on because the color could not be further from what we were expecting. It's actually a really cool and unusual fun fabric, but not really describable as any shade of green which is what I was going for. It's more of a beige tweed whose tiny plaid upon careful examination even has slightly blue threads.. or is that lavender? In fairness to the manufacturer, I tried and tried to get a photo with lighting that accurately represents this fun and unusual color to no avail. For a proper review I guess I should have my son put it on and take a picture in daylight. But they do need to change the color name at least to "champagne tweed" or something. No idea whose job it was to call this color "celery". ;p

Sharp and Expensive Quality Tuxedo for special events!!
Size: Small, Color: Black
I researched for several tuxedos for my son's prom, we chose this one, and I'm very glad that we did! The fit is nice, the durability is great. Very classy looking! The quality is really surprising for this price, it looks like a $200 dollar suit. My son is very picky and was very pleased with this tuxedo. The seams are very good and all the buttons are correct. We did receive the tie and everything that was supposed to be with it as I know reviews were saying they didn't get certain things but we did. I really like the adjustable waste because my son is very slim, but tall and has a long torso. This Tuxedo allowed him to be super excited that we have everything we need for his first prom! True to color as we purchased the black and it is sharp!

Impressive suit for the price
Size: X-Large, Color: Navy Blue
Order suit in my normal size (44R) and it fit perfectly. I’m 6’1” and the pant length set at the correct level. Quality fabric and stitching is well finished. Pants are comfortable at the waist with enough flex to be forgiving. Very good deal for the price…suit, vest and tie.

Great for tall, slender teenager!
Size: Small, Color: Light Grey, Size: Small, Color: Light Grey
Finding a suit for a tall, slender teenage boy is about as hard as climbing Mt. Everest. Until I found this one!! I was so pleasantly surprised that this suit fit my 15 year old son like a glove. He is 5'10'' and 140 lbs so he needs pants with the proper length and smaller waist. While the waist was slightly big, he didn't need a belt and the pants fell perfectly with a pair of Nike tennis shoes. I ordered a size small and would say the pants were a 32x32 but waist was probably more like a 31. Jacket and vest were a great fit as well. High quality and easy to steam to get the shipping wrinkles out.
