No the power and megabomb both make your quad quieter. Its also helps with airflow. But i dont know how it would gain HP? If it did it would be only 1 or 2 HP. You get all your power from a slip on exhaust!

 

Yeah they existed. Iv seen them on ebay. $300 bucks though!!! Lmfao

 

Looks like some of you guys need to dig a little deeper, there is no Megabomb atv header. They are only availible for 4 stroke mx bikes

 

Wrong, If you got all of your power from a slip on exhaust, how come the headers make such a big difference for the 450s and the 660s and even ds's?The silencer is all sound if you have a stock header, Yea, sure, youll gain some mid range, but nothin too big.The rappy 350 is different though.It shows results without an aftermarket header, but it still shows better with one.If the begining of the pipe cant let any air out what is the end going to do for it?Think about it, if you pinched a straw at the beginning and guaged the end, what good is guaging the end going to do for you if no air is coming through?That is a good example of how exhaust works.

 

Fasterthanyou, Explained Very Well

 

the mega bomb isnt made for the raptor 350. i myself am getting the power it has good gains with after market parts!!
