Hi, wanted to find some specs on the conception of the FMF Megabomb primary pipe.

With some computer simulation my oncle found that the optimal diameter size at the port would be 34mm and the lenght between the beginning of the pipe(port) and the expansion chambre (bomb on the FMF megabomb) should be 325mm.

So could someone can tell me for the

FMF megabomb for CRF250L 13-1 and for the 17+ model, diameter at the port and lenght of the pipe between beginning of the expanson chamber.

Thanks and sorry if the english is not that good i'm a frenchy canadian :-)
