what pipes will fit my header??

[Blue250X]

i bought a 91 250x and it came with an fmf megamax pipe and some header. my question is, what all mufflers will fit my headers that will give me more power than the fmf

Any slip on made for a 250X/300ex if your header is the stock one.

[Blue250X]

its aftermarket

any 300ex/250x slip on exhaust but u have 2 do what i did and cut about a foot off the megamax header but it is worth it.
