oh yeah yoshi does...he got a full yoshi exhaust, k&n filter and FMF jets, and holeshots on the back...that's it and the 400 is pretty quick...he raced a banshee ( i think a '02?) and beat it (barely..but still beat it haha)
For the money I think the HMF slip ons sound Good.
I had a DG on my 87 Kawasaki Tecate4 and it sounded Awesome. And it held up for alot of years untill a rollover and then we bought a FMF. Thats what went with it when we sold it
My friends 400ex will smoke a blaster pretty good run on a Banshee. but our other buddy has a 450R the banshee won't touch it, He smoked one at Busco beach's drag strip by about 3 bikes....GO HONDA!!!!
On the MX track those old 2 strokes are slow. Todays tracks are made for todays bikes and quads. I have seen 400ex make a blaster eat dust. never seen a banshee on the track. In a wide open a stock banshe should beat a 400ex even with mods. A 450 will beat all them old 2strokes except for a Quadzilla. But thats a 500cc 2stroke.
