Why just fix the leak when you can eliminate the choke points?

I haven’t been very motivated to work on this project so it is going pretty slow. Keeping busy with some other things that I’ve been wanting to get done like changing out a bad TPMS sensor last night.
I have cut a little stainless and will load a few pics.

I worked on this for several hours yesterday with VERY slow progress. Currently regretting my decision to go this route, but not enough to change direction.

Here are a few photos of where it is sitting now. There is a shot of the 3” pipes from the front and rear. Also the front plate of the new chamber with the double wall. I’ll be packing the gap between the walls with mineral wool.

I intend to make a little more progress this evening.

Progress was much better last night. I cut out a top and side plate for the inner chamber before supper and went back out after supper to tack them in place.

That went so well that I welded up the seams 100%.

And THAT went so well that I cut the other side plate and welded it in place.

Weld quality with the heavier sheet is SOOO much better.

Last night went so well that I now have a little motivation back for this project.

I put in a stiffener across the side plates to try to prevent any vibration.

Then I added a stiffener from top to bottom.

I drilled a hole in the bottom plate before welding it in so that I could plug weld it to the stiffener.

The progress last night wasn’t as good as the night before but still ok.

Next I’ll be test fitting it again to make sure everything still looks good and cutting the holes in the outlet end plate.
