headpipe difference?

[bigblock]

What is the difference between the stock headpipe and aftermarket ones? Not trying to be stupid , I just was wondering
since their is only one pipe how much more exhaust can you flow?

I'm running the two brothers slip on, but I want more power
I just dont want to lose any bottom or midrange any suggestions?

I guess what I'm really getting at is I hope I didnt just waste
my money.....:)

the aftermarket head pipes are bigger in diameter.

imo, the head pipe on both 450's are fine, its a waste of money to buy an aftermarket.

They also have a different bend. I believe a tighter bend will help produce more bottem end then a more open curve, but dont hold me on this!:macho

by tighter bend, do you mean shorter?
