CMB 45RS header length?

[Sean Janne]

I'm about to install this CMB 45RS with a CMB Quiet Pipe, which is a muffled pipe into my 39" mono. What is a good glow plug to "weld seam" length to start with?

 

[Danny King]

9.5"

MONO,,, 10-3/8"

 

[TimothyJones]

Yea 10-1/2" depending on other factors though... You can always go shorter and very well may end up at 9-1/2"

 

[TimothyJones]

I think mine is at 9-3/4", 50% nitro,surface drive,X455/3, can't remember what the ex timing is.

 

[Sean Janne]

Thanks! Should the measurement be to the rolled seam on my pipe, or where it flattens out before that rolled seam?

1. on a pipe that has a flat section like that, I measure to the center of the flat band.

I also measure from the center of the cylinder, to the widest point. Not from the glow plug

 

[moparbarn]

good info, RRRick. so many different ways & places to measure to/from. ANY pipe measurement info should include what you posted. i measure like you do, straight down the centerline of the pie, to the centerline of the cylinder - 1 straight line.

So, I should measure from the "C" on the engine to the middle of the flat part on the muffler?

Not sure where the "C" is on your engine case, Could be CMB Or C so let's just say Center Of Cylinder

M

B

OK, looking back at the picture provided, measure from the V in the M of C

M

B

Hey RRRobin,

Sean,

Here is a pic of his own D Mono, just so you can see the kind of work he does. Not too bad for an old Coastie.

CHEERS !!! Bob
