ok ive narrowed my exhausts down to the DMC or the WB pro meg for the 400ex.... if anyone has dyno runs of these pipes with a 400ex engine (gt thunder has the dyno runs of full race exs, i want stock 400engines) if u dont have any its fine but please tell your opinions on the two pipes or what u know about them like how much faster or etc etc.... and please tell the pipe you would most likely go with (the mods im doing are whichever pipe i get, modify my airbox with drilling holes or something, put filtered plugs in the holes, k&n filter, outerwear, jet kit with proper jetting) thanx please reply even if its the slightest info im ordering my pipe tomorrow... this will help me decide on which one to get thanx again

I AM TELLING YOU MY YOSH MAKES MORE HP AND TORQUE AND ITS CHEAPER THAN THE DMC ....CANT SAY ABOUT THE WB......GOODLUCK IN WHAT EVER YOU DECIDE .....

With the mods you are planning the Supertrapp IDS2 would be OK with a 14 teeth front sprocket but if You are planning to bore out your motor and do other things with it go with the DMC.

 

my white bros. pipe is awesoom, puts out alot of power and torque
