I'm getting a full Belanger exhaust system installed as well as a smaller under drive pulley right now, and seeing what I can expect out of the viper. I wanted to see what the stock rwhp is for the RT/10. I know it's advertised as 450 hp, and I assume that's to the crank. Just not sure how much hp loss there is. Talking with the tuner, I'm hoping to get an extra 80-100 hp with the full exhaust, pulley, and a performance tune. Does that sound accurate?
