Exhaust sounds awesome on my kx500. Could also feel a little more power in the bottom end!

With a clear and stylish design, the 304 Silencer will make a lasting impression. The slightly longer body offers reduced noise output when compared to the R-304. Its perfectly constructed lightweight cylindrical canister, combined with the brushed aluminum body and stainless steel inlet tube and end cap, give you a silencer that looks as good as it performs and ensure that a truly unique riding experience is in store for you. The 304 silencer is recommended for most two-stroke applications.

Form, fit and finish is of a quality that I'd expect. I can't say anything bad for the silencer. It did just as I wanted, I was running a shorty silencer, but with my SXS 300 kit it was a little to punchy for my tastes. The longer silencer moved the powerband higher into the RPM range and the hit was a tad softer. It works for me.
Fitted on: 2009 KTM 250SX
pro-circuit products have been on my race bikes for 20 years they hold up well look good and perform well . very happy with pro-circuit.
First silencer I ever bought that actually improved performance in conjunction with a pro circuit platinum 2 pipe. Power delivery better across the board. Buy it !
long live the 2 stroke! pipe rips and stays looking new for a while- cover it with WD-40 when you clean the bike.
Was great paired with e Pro circuit spark arrest or, and was very good power booster, plus looks good on the bike, and seems to be okay durability, but not as good as FMF. By far one of the best power boosters in terms of 2 stroke pipes, I've ever used.
I bought this silencer because it was rated really good and the price was great. It is not as loud as i was hoping on my kx 85 aboutthe same as stock but really makes a difference in power
The 304 really lets all my horses out, top and bottom end show significant power increase. Had a spark arrest on before. Very snappy on the pipe, no back pressure lost. No change in spark plug wear. Hidden behind the number plate, very neat to the bike. SOUNDS SIKK!!!
i bought these to pair with a set of shearer inframe drag pipes they fit like a glove and took the banshees crackling sound away and gave her a extraordinary exhaust note in between a 4 stroke and a chainsaw sounds like an angels soung to my ears.
good silencer sounds awsome with the pro circuit works header
Sound good and good price
it is noticeably quieter , but dose not take away any preformane, all around good pipe
This looks like its going to be a good silencer, it was a little hard to put on my 2007 kx 85 you have to force it some it was off a little bit. Havent got to ride it yet or start it up but im going to tommorw. But by hard to put on i mean you have to push real hard and it pushes the rubber muffler joint thing some and it goes back a little extra.
this silincer was a great buy, it quieted my bike down a bit and made it sound awesome, and i didnt even need to rejet my kx 80, there was a major power increase throught low to high rpm's the only problem was that the silincer didnt fit in the stock position and it wouldn't let me put my side pannel on right, and i had to modify the side pannel to get the new silincer to fit in but it looks alright, the silincer didn't look like it does in the picture but whatever, overall a great buy
Bought this with the Platinum Series Pipe for my 2000 YZ 250. It bolted right on, fit perfectly and performs great. I love the way this make s the bike sound! It is very easy to re-pack and the finish is durable. Big thumbs up!! See my review on the Platinum Series pipe for more...
