odaen Posted August 13, 2005 Report Share Posted August 13, 2005 I run CPI's and am very very pleased with them. Never dyno'd or ran my bike with anything else though, so I'm open to try stuff. Quote Link to comment Share on other sites More sharing options...
FASTOYS Posted August 13, 2005 Report Share Posted August 13, 2005 If it is a stock or mildly ported bike i would say T5s or Pro Circuits would make you real happy. I have ran both and had good success! Pro Circuits actually run their azz off . T5 might have alittle edge on top end. After that you move into Cpi's and Shearers!

strokrbanshee1 Posted August 13, 2005 Report Share Posted August 13, 2005 I used to run Pro Circuits and they do run hard for what they are... Quote Link to comment Share on other sites More sharing options...

BUT, they were not on his list!! IF he needs even more power maybe he should consider the almighty Rockets also. Quote Link to comment Share on other sites More sharing options...
PassionRE Posted August 16, 2005 Report Share Posted August 16, 2005 (edited) If your engine is even moderatly ported, for off the shelf pipes, nothing even comes close to a Shearer for top-end..even CPI is a dismal 2nd....unless you consider some of the builders that are just stamping out versions of Matt's designs and calling it there own creation...Jim Edited August 16, 2005 by PassionRE Quote Link to comment Share on other sites More sharing options...
Ultimateduner Posted August 17, 2005 Report Share Posted August 17, 2005 Out of the ones you listed the T 5 pipes do good on top-end. But I ran some old school fmf top-end pipes hauled ass, until the side of the pipe cracked. Uh well it was like a ten year old pipe. Anyways depending on your mods I'd perfer either CPI s or Rockets. I never talked anyone with shears but heard their good too. Quote Link to comment Share on other sites More sharing options...
BansheeBrian Posted August 17, 2005 Report Share Posted August 17, 2005 Pro-Circuits do run well but you have to keep them in the powerband or you're hit. They don't recover very well once out of a certain RPM range. That's why I'm going with some rockets. Quote Link to comment Share on other sites More sharing options...

That's why I'm going with some rockets. 405770[/snapback] Pro-Circuits, T5's, and FMF's all have what I'd consider a very forgiving powerband. They develop a good deal of torque at lower RPM's than what I've seen from CPI's, Shearers, or even Rockets. This allows for far more sloppy riding. My stock stroke ported shee with T5's developed torque almost 1000 RPM lower than my 4mm ported shee with CPI's. If you're having problems falling out of the band with PC's, then maybe you need a gear change or something, because your problems are gonna be worse going with Rockets.

rocketboy Posted August 18, 2005 Report Share Posted August 18, 2005 (edited) ive ran pro circuits i n the past on my she and never had any problems making them stay in the power range, they actually pull higher and slightly broader in the rpm range than t5... but t5s have that nice hard "hit" that makes riding fun Edited August 18, 2005 by rocketboy Quote Link to comment Share on other sites More sharing options...
FIRST BANSHEE Posted August 20, 2005 Report Share Posted August 20, 2005 What other pipes than what i had listed above is better for top end 403885[/snapback] from the dyno sheets iv'e seen, shearer and grand river racing out of frame drag pipes seem to peak the highest.
