Here With Another Question

I just received a OEM Exhaust assy for my Vmax. No scratches and no dents. I'm in the process of cleaning them up and repainting some of the paintable heat parts. I came across the small bolt areas on the secondary cross overs (What I'll call them pipes.) Might be a dumb question, But.... What are they for?

Beauty shrouds. #13, 14, 17, 18; screws to affix via the welded female fittings: #21, 22, 23. Part #'s 30, 31, 33, & 34 are access bungs to the exhaust interior, for exhaust gas analysis. Note they are on the front cylinder header pipes, this is for cylinders #2 (left front) and #4 (right front).

I just knew it had to be something simple. My feeble Ole' Mind Thanks You

If they go right through the pipe then they could be where the factory attaches the meter to set the CO.

Okay, thanks. While I do the swap, I'll check them...
