Your new here arent you!
Like I said, it had a better torque curve and in most cases more hp. We have done rear wheel dyno and crank dyno testing. As well as real world riding and drag racing to compare these pipes to others.
At 185 degrees duration this pipe outperforms everything else. 185 degree exhaust duration on a banshee is designed to make hp to 9k rpm. PC pipes max out on hp at about 8600 rpm. If this guy is running these now, and wants to look at a T5 and a shearer, he is gonna pickup anywhere from 1,000-1,500 rpm. If he is really going to make more power with these upgraded pipes, then he grossly overlooked his original pipe decision and completely picked the wrong pipes for his setup (porting) in the first place. I am well aware of how pipes affect power, and well aware of what pipes do what for power. Admitadly I do tend to gravitate towards gainning knowledge on low-mid pipes as I am more interested in that type of power. But a jump from pc's to t5's or a shearer is a bit odd in my book.
Here is one of those real world drag race tests I am so unknowing about. Featured here is a ported 350 with dual 28mm tm's and pro circuits (green bike), then a cascade built 4 mill stroker with paul turner mids (yellow bike), then a ported 350 with 2 into 1 35mm pwk and paul turner mids (black bike), and finally my bike the blue light special with a ported 350, 2 into 1 pwk 35mm carb, and pro circuits. P.S. I win! It is very important to match the pipes to the motor they will be bolted to.
