Does anyone know anything about any of these pipes? A&S pipes, CPI pipes, Fast Forward motorsports pulse-charger pipes. Looking for a good top-end or high rev pipe. A&S claims 7more hp than Toomey t5s. Thanks

 

Don't have any info first hand on those pipes, but I know a couple of local engine builders using Kenny Roberts in-frame pipes, they claim more hp than the toomeys. I saw a ported 350 run really well on them this weekend in Mexico, but have no contact info on Kenny Roberts.

 

i am gettin engine work done for my banshee right now form dan hull at A&S racing, he has done a lot of research and testing on all types of in frame pipes and drag pipes. i have never run any of them but i am planning on gettin soem of the drag pipes he sells, which are CPI drag pipes pretty soon, and the inframe pipes he sells are CPI tukin pipes i think, get bluebanshees website adress, and he has some pics of those drag, and inframe pipes on both his bikes on his webpage
