horsepower difference b/t o/r x and h

I have gone from Dr. Gas X-pipes to H-pipes to Bassani X-pipe and the Prochamber. You will not really feel any difference in power. I quess the only way you will feel is if you were blown or sprayed. I say stay with the H-pipe. Has more rumble for the V8 sound.
 
well i went w/ the o/r h-pipe bc i screwed my x up, but its ok..i like the deep sound of my new h, it sounds great, i miss the scream of the x though i wont lie...i cant really feel the difference b/t the two..but i can say that im satisfied...thanks for the input guys

I had the Dr Gas at one time and now I am waiting for a MAC Hpipe to come in the mail. I really hope I dont lose noticeable power between the two. 5-15 seems like a lot to lose if it is correct.
