Looks like its gonna be test as we get them. Ill post up results of all pipes vs. modded stocker. Both dynoed that day that way you can see how they all compare vs modded stocker.

Here is the fmf 4.1 ti that Jake sent me. Good gains across the board. Peak power wasnt that great but killer bottom and topend. This was tested before my last dyno graph. Enjoy. Ill have a few more pipes next week. Dasa full system from Jake again and Hmf full system that I bought myself just to test.

Pretty much would of put my bike at 52whp after my oil change. Bike feels way faster with it on. Not to mention it looks and sounds killer.

The full system is worth it. More power across the whole board. Close to double the whp of the slip on

I think the fmf full system is a waste. It will lose power over slip on Im pretty positive. Id say right now your best choice is the dasa or hmf. Id say the hmf. I have it on my machine and it comes with a very nice quiet core and sounds killer. Power was very good to. Ill post those results soon enough. Gains across the board much better than just a slip on.

driver311 what do you think of the fmf mega bomb header for the 525 xc. Have you dyno anything like that. They claim lot off bottom end power.

Craig, we have not Dyno'd one on a 525, we have dyno's them on other bikes, in fact the "BOMB" and can, lost power on and LTR, we removed the Bomb head pipe, and istalled the stock hea pipe and tried again and the slip on made power, If anyone has one Driver and I would love to throw it on the rollers and see what it makes

No one will send one becuase they are afraid of the results. We need to test one though to show people not to waste 700 on a power robbing system. How can fmf sleep at night. The fmf megabomb lost power on the ltr450 and the ds450, but the slip on did about 1-1.5whp on both machines and the ktm. Ill be testing a few more pipes on my sx next week. Dasa slip on, dasa full system and ill post the hmf full system.

Ya I am curious if the mega bomb will lose HP on a carbed bike like it will efi bike. I hear A LOT of people SWEAR by the MegaBomb and 4.1 on all the dirt bikes a lot! Im just curious if a carb would perform different.

Thats rediculous. Carb or efi, it will be the same. Ill prove it once another one is sent to me. So far its 2 strikes for megabomb. Its a sales gimmic!!!! The only reason pros run them is for sponsorship reasons and also they are one off custom ones built by their personal builders(not fmf). I know that for a fact a pro rider told me straight up that his was a one off because the standard one made no power.

I think I have one on the way for the xc, so we will see.
