Car Chemistry Header Baffle Kit - Sound Performance

In the first of these two images you can see I'd positioned the second disc onto the core tube so that it fit snuggly to the inner wall of the header tube and made a second mark.

The discs are tack welded to the core because they can and will move a bit during assembly. The second image shows disc 2 at the mark and in its correct position.

With the first and second discs in place I then started the third and final disc onto the core tube and gingerly slid the assembly into the header until it was stopped by the first disc contacting the header wall.

Since the discs, at this point, were not tack welded in place I made sure to handle the assembly carefully. The last thing I wanted was to move a disc without realizing it. It's important they contact the header wall snuggly. If not, they may vibrate against the wall under exhaust pressure and end up driving ya nuts.

With the third disc located and marked I pulled the assembly out of the header tube so I could move on to the next step.

Car Chemistry includes a couple of restrictor plugs as part of the kit--one drilled, and one solid.

The restrictor plugs will help in sound adjustment by either slightly restricting the flow of exhaust through the core tube, forcing a portion of that flow into the chambers created by the discs, or in the case of the solid plug, rerouting all the flow into and through the chambers, thereby reducing the sound even more.

I opted to use the drilled plug at the inlet side but passed on the solid one for the time being. Heck, I don't want the thing too quiet, ya know?

With the first assembly completed I figured I'd better get things welded into place before anything moved on me. I set up my welding table and readied my Miller.
