[mrgary]

hi all,,need a little help on a pipe lenght,,i would like to know where to measure to and how long on a cmb tt pipe for a 21 rigger,,thanks alot and just post here please,,,gary

the most common measurement is from the glow plug to the fattest part of the pipe. if your pipe has a flat section in the middle, between the tapers, measure to the middle of that. can't help on a length, but i'm sure someone else will chime in.

no problem, one thing though, if you have a side or front exhuast, you need to measure the header through the centerline around the curve. i've heard some say to bend a piece wire to shape, then straighten, & measure that. with my ob's, & their multiple bends, that seems more accurate than trying to get a tape measure to conform to the curves .

Grim used to make a gage for the NR 180* header. THey are really handy if you can get your hands on one. Once I sell all my NR's, I'll probably sell the gage, too.
