I have a 2004 400EX and I was wondering if I got a WB E-Series silencer and a headpipe would I need anything else from the engine to the silencer besides those two things like a midpipe and if I did need a midpipe would it come with the complete system?

the mid pipe should come with a complete system u dont need anything else, except to rejet but im sure you already knew that

 

Would I need a midpipe for a slip on silencer?[img]i/expressions/face-icon-small-confused.gif[/img]

 

if you just get a slip on, you might just want to buy an exhaust gasket. but that is it.

 

the slip on will come with a mid pipe. any wb pipe can be a slip on I believe. so, if you want to buy the muffler now, you can buy the header a little down the road.

 

this isn't the case with the pro meg headers. if i was to buy a white brother pipe, i wouldn't get any thing else than the pro meg headers either. they are pretty good.
