Breaking the fourth wall... of parking.
 
First of the flapper valves came in. The other one is doing the literal hot lap around Western Canada.

This thing opens lightening fast! Startled me. I'd almost put it on a Hobbs switch once it senses boost it flips open. Decisions. Decisions.

Had to order them from two seperate sellers. Since at the time each only had one available.

Sweet. I’ve got the Dougs Headers sliding knife version on The Juggernaut. I’d be interested to see how each holds up long term.
I’ve heard that the flapper valve style like you have can suffer from sealing issues once they get a bit carboned up.

I am drilling holes in them since they are inline, not cutouts, so it shouldn't be an issue.

Got the day off from course. So I decided to start plotting out the x-pipe.

Well this was a PITA to build. Especially the tight pinch points.

Fusion (cold) welded the inside of the two mating pipes to make it easier to assemble. Worked out surprisingly well using a stubby #5 and back cap.

The goal was to have the inlet side 3.75" CL to CL, and the exit at 4.5" CL to CL. It was also made deliberately asymmetrical as the stock pipes are askew, favouring the PS if I remember correctly. The new mufflers are good being angled since the cars come with either bullets or case mufflers and there is lots of space.

Overal the fit-up was so-so, so the welds came out a little inconsistent. I also I am pretty f*cking tired. I will probably go over the inside with a penetrating pass to ensure... err... penetration. I will also be adding a brace between the two connected pipes.

One step closer.
