1320CaliKing Posted April 28, 2011 Report Posted April 28, 2011 Which pipes give you more mid to top end cpi or shearers Quote
Hilarious Posted April 28, 2011 Report Posted April 28, 2011 from my experience it has been the shearers. Quote
joee20002 Posted April 28, 2011 Report Posted April 28, 2011 from my experience it has been the shearers. X2 I think cpis are great for a dune bike... Quote
J-Madd Posted April 28, 2011 Report Posted April 28, 2011 Which pipes give you more mid to top end cpi or shearers Depends on exhaust port duration. Quote
1320CaliKing Posted April 28, 2011 Author Report Posted April 28, 2011 My bike has a cool head with 19cc domes it has a pretty good size port on it not sure either drag or dune, it has v2s on it n on keinin pj 34's I want a pipe that'll give me good mid n good top end I like duning but I like to drag once in while Quote
sleeper06 Posted April 29, 2011 Report Posted April 29, 2011 I thought by the 1320 in your sig you were a 1/4 mile guy,shearers all the way Quote
Big Bucks Posted April 29, 2011 Report Posted April 29, 2011 i had a 7 mil stock cyl that was race ported by white knuckle racing, and on the dunes the cpi performed better than the sheere, but on the dyno the cpi made 9 hp less than sheere, but the curve was alot better with the cpi....., i thought i might add those were inframes..... but it realy matters on your exaust port timing jmo Quote
1320CaliKing Posted April 29, 2011 Author Report Posted April 29, 2011 Thanks guys for the info Quote
Sandjunkie29 Posted April 29, 2011 Report Posted April 29, 2011 I am new to this sight and it's amazing how much info you guys have I hope that I will be able to share what I know witch is not much I have v3s and CPIs and my bike is all top end the only thing I did not like about sheers were all the welds on them I don't know if that has changed Quote
1320CaliKing Posted April 29, 2011 Author Report Posted April 29, 2011 The welds on shearers are good just like cpi's but if your bike is all top end you should which over to shearers cuz those pipes are ment for top end I have a friend that has cpi's n another that has shearers there's not that much of a difference. But there is a difference you can feel and it does matter on porting intake n exhaust Quote
stroking Posted April 29, 2011 Report Posted April 29, 2011 ok what about pro powers,are they better than CPI's ? with a 196* exhaust what would be the best of all out dragging ? Quote
J-Madd Posted April 29, 2011 Report Posted April 29, 2011 ok what about pro powers,are they better than CPI's ? with a 196* exhaust what would be the best of all out dragging ? Shearers or RDZs for that exhaust duration, imo. I don' t know much about power pros. Quote
06specialedition Posted April 29, 2011 Report Posted April 29, 2011 I don't think you could go wrong either way. They are both great pipes and both pull hard on top. I run CPI inframes on my duner and I like them. And CPI is local to me. Quote
BigRed350x Posted May 1, 2011 Report Posted May 1, 2011 Shearer pipes. Snipers would be my next choice, then CPI's. CPI's SUCK ASS for access to your plugs and pipe routing back around the filters. I only run them as a last resort. Quote
stroking Posted May 18, 2011 Report Posted May 18, 2011 heard RDZ pipes smokes both of these with ease Quote
