I'm hoping someone with an FMF PowerBomb header on a WR/YZ400/426, can tell me the diameter of the 'fat' section of the header. Thanks, Chris.:cry:

I have a SS power bomb on my WR 426. Outside diam is 1.622 in. With my dial gauge just before the mid pipe junction. Same Diam. at the header.

The header pipe size is roughly 1.6 inches. The FAT part is 2.125" or 53mm. It is 2.75" long, plus .5" on each end to taper back to 1.6, and is about 8" from the exhaust flange at the head, measuring along the pipe center line.
