I modded my 400ex stock header today and put it back on i think it has a little bit more low end but that might be all in my mine. all the neigbor hood kids where out side playing so i decide to fire it up with just the header and it sounded like a drag car it was so loud my ears started ringing and the kids freaked out it was awsome
