Which exhaust pipe has more power? The White Brothers S Series pipe, or the FMF Mega Max 2 pipe, I'm going to get one for my 00' Honda 450 Foreman, I'm also adding a K&N Air Filter. Is there any thing else I can get? or need?

 

IMHO the megamax 2 is junk. Very Very poor quality. Mounting brackets breaking, and melting plastic from poor fit.

and K&N filters are junk. They don't filter good at all, go for a UNI, or a stock one.

 

Aaron,
The ORIGINAL Megamax was the one that was junk. It had a lot of problems. The Megamax II is far higher quality. It doesn't have a clamp at the header it is just a slip together. And the welds are far better. Trust me, I really rode rough with mine and it held up awesome.

NOW for the bad points: They're heavy, you won't lose any wieght with one of these.
You really can't run them with the spark arrestor in place. If you do, you'll have about the same power output of stock. At least I did on my 400ex. So I ran it wide open.

 

The WB E-Series S-Bent (which just means a slip-on insted of the whole system with header) is far better in my opinion. I have been researching pipes for months before I got my E-Series, which I am very happy with. It seams to have the most power output with out being to loud.
