Just wondering if someone could estimate how much HP I will be making:

HMF Full Sport Exhaust
HRC Kit, minus the cam
Curtis Sparks Air Filter
13 Tooth Front Sprocket

I was thinking around 42 also, but I thought stock it was 38. Now after researching more for the stock HP for a 2005 TRX450R I have seen statements that range the HP from 32-38? Anyone know what the stock HP is for sure? thanks

stock 04/05 was 37hp and stock 06+ was 42hp. with the HRC kit and full exhaust you could have 42-45hp tops, the stock piston is a slug holding back a few hp. add a cp or je 12-1 piston and it will be around 45-47hp
