Hi folks !
Lot of different exhaust systems and dyno curves has been released for 2004 R1 at this forum...many of the horsepower gains are just claims...some have released real dyno curves which are more realistic...anyway it is real sad that many of you have used only downloaded general maps for power commander III...only few of you have done the real mapping work for individual bike using a lot of expensive dyno time...but believe me...this is the secret for the real power...
I have had a long co-operation with my local Yamaha dealer and they have found with their dyno, the best slip on hp gain has been found from the Yoshimura tri oval and custom mapped power commander III...again Yoshi...the yoshimura was my choise for 2001 R1 also !!!Ok...of cource they have had no possibility to test all the pipes but for instance Acrapovic gave 1 hp less...
The Yoshi tri oval shape is a little bit strange for 2004 R1...some likes the shape and some not...I have not seen much pictures from tri oval pipe and 2004 R1 at this fotum...but...believe me...after hard study on dyno...this pipe is a real killer...
ALMOST 11 HP (10.77 HP) POWER GAIN compared to STD bike(Yoshimura Tri oval slip on and power commander III with special custom map for individual bike)!!!
