Yoshimura alpha measurements needed

[wreckwriter]

Anyone have a Yoshimura alpha full exhaust on a gen 2 that currently has their plastics off, or better yet has the exhaust off? I need a couple measurements for my Woolrich setup.

I need the internal pipe diameter in mm and the distance between where the pipe attaches to the engine and the center of the right side O2 sensor bung, also in mm.

If anyone has this info I would greatly appreciate it!

You can get the overall length by holding a piece of string along the pipe, then measuring the string.
You can also remove the muffler and midpipe, then measure(calipers) the wall thickness of the collector pipe on the end of the header, as all the tubes should be that thickness.
Double that measurent, and subtract it from the outside diameter of one of the header downpipes.
Done.

Indeed. Hoping someone who has one already has their plastics off so I don't have to pull mine again. I will if I have to of course

Anyone smart enough to get the measurements from this? Got this from Yoshimura.

I get 45.847mm for the I. D. of the tube. Guess I'm not going to pull the plastics for the length

OK, here's the answer

Length 640mm
I. D. 45.847mm
