Chris's new build of an MX5 based car

[CTWV50]

It's a straight through pipe so completely unrestricted flow of gasses down a 2.25" bore pipe for my little 1.6 should give it a throaty rumble. lol

Today I got a few hours in the garage so I removed the collector lambda bung by making myself a 23mm spanner from a 13/16th of an inch spanner. Never met a 23mm nut before!

And then removed the heat shield to discover two shield mounting brackets had cracked during removal. We'll we all new that would happen. And then noticed some cracking in one of the tubes near the collector. So this was a good excuse to get the welder out and repair the crack, beef up the rest of the collector weld, weld the pipes together higher up to add strength and remove the rest of the shield brackets.
