Ultimateduner Posted January 15, 2004 Report Posted January 15, 2004 ebay auction cpi pipesOn the ebay auction they say that with individual aircleaners and a stock motor the cpi inframe drag pipes can increase your speed by 16 hp is this true? Quote
shortys racing Posted January 15, 2004 Report Posted January 15, 2004 ebay auction cpi pipesOn the ebay auction they say that with individual aircleaners and a stock motor the cpi inframe drag pipes can increase your speed by 16 hp is this true? hmm, i wouldn't say 16 hP by doing nothing. but with a shaved head, timing plate, and aircleaners then yeah prob.

Stylemaster Posted January 15, 2004 Report Posted January 15, 2004 CPI in frames are really good pipes. i wish i had a set i will hopefully by teh end of the year Quote
Ultimateduner Posted January 16, 2004 Author Report Posted January 16, 2004 they also say that I need dual airfilters is this true? are they good pipes for the dunes? how much bottom end will I loose. Quote
Banchetta Posted January 16, 2004 Report Posted January 16, 2004 I believe a 16hp increase at around 10,000rpms...the stock exhaust drops off early and loses power after 6500 while the CPI's will keep making it until 9-10K..thats why aftermarket pipes make the shee have about 10mph more top speed.....peak hp of stock pipes to peak hp of CPI's should be around a 10hp or more difference....

Ultimateduner Posted January 16, 2004 Author Report Posted January 16, 2004 so is it worth the money? since my banshee has the old school fmf pipes now much more top speed do they give me Quote
thecabinboy Posted January 16, 2004 Report Posted January 16, 2004 Would CPI inframes work better 4 me or should I stick with what I got? It made 60hp on the dyno with my 22"razrs. I do desert riding and dunes mostly. Quote
spoin39 Posted January 16, 2004 Report Posted January 16, 2004 They might give you more power but not much in top speed. You need to change the gearing for much of a gain there. What do you need top speed for? Quickness is more useable than top speed 95% of the time unless you are desert racing. Quote
Ultimateduner Posted January 16, 2004 Author Report Posted January 16, 2004 I know they give you alot of top end but how much bottom end will I lose Quote
Leadfoot350 Posted January 16, 2004 Report Posted January 16, 2004 cpi pipes rev out sooner than t-5s. They make much more usable power through the mid to top end is what I heard from rudy kurtz and he said that with my motor the way it is now I would get 6hp with cpi pipes. I think I like the out of frame pipes cpi makes because it gets them away from my knees and looks cool too. Quote
