What pipes do you usually run on your 446? Is the pipe choice stroke related? A 66mm 7mil is only 417cc. Tone it down? Never. Thanks for the reply, Nick

I just used the blue rubber collars. Honestly, they fit so well you don't really need collars Not positive, but I think I used 80mm springs . Nick

I went back to my CPIs sbs after I figured out my shearers were bbs and not sbs. I traded a kid a set of t5s for them; he had a 410 stock stroke so I figured they were sbs; wrong; no wonder he didn't like them. I do want to build a bigger engine and run these pipes, I just need to know how big. I've heard anywhere from 440 to 500; I need to know for sure. I've been running CPIs for 4 or 5 years and love them; just looking for something a little different; maybe go with some snipers later on. Nick

Hi everyone, I'm new to this forum, but not new to banshees or forums. I live in Klamath Co Oregon and do most of my riding at the Oregon Dunes I'm planning a new engine build using shearer if bb s. My ? is how many ccs do I need to make these pipes work properly? I ran them last year on a 410cc stock cyl 5mil and they were very inconsistent. They would make more power climbing hills than on the flats; like the engine needed to be under more of a load to make the pipes work. Thanks in advance, Nick
