Pro Circuit silencer question

Most of the pipes ive looked at i have to order the silencers seperate so i didnt know which ones to go with. I thought there was 2 different ones but i cant remember correctly and i cant look it up on my phone.

 

Yeah they offer a 304, which I think is not spark arrested. And they offer a 296 which is spark arrested.

 

Just depends if the area you ride in requires sparkies or not...

oddly enough i ran the 296 silencers and it felt like it has a better pulling bottom than 304s.then i read where a serval was dynoed and the 296s made more hp than 304 on a dyno.so i wasnt just going retarded lol.

I have the 296 spark arrested silceners and I love mine!!! No loss in power and fairly quiet compared to other silencers.

What would my jetting be with the pro circuits? I am completely stock now with stock pipes and stock jetting and it runs and idels perfect.

I have stock carbs with stock jetting

Stock air box with lid an uni filter (soon to be pro design with k and n)

elevation is around 500 feet.

 

What would my jetting need to change to with the pro circuits? Just trying to get an idea so I know what jets i should order so I can try and get them all in that the same time.

I got my PC pipes with the 296 spark arrested silencers from JC Motors online for like 530 shipped to me. Cheapest around. I have pretty much the same setup as you and close elevation. I have vforce 3 reeds and lid is off the air box. I am currently running 320 mains with 27.5 pilots and air screws and needles in stock settings. Runs great!! Now that it's getting cooler outside I'm going to change mine to 330 mains and 30 pilots. pro ciruits like big jets. They make tons of power rev really high like 7500 rpms's!! Good Luck!

Also, where is the best place to buy pro circuit pipes? I have been looking on ebay, motocrossgiant.com, etc and it looks like its going to cost me around $580 or so. Any place I can get PC pipes and silencers cheaper?
