This is a Mitsubishi sigma with a big block V8 Cleveland motor jammed in between the strut towers.
We were appointed the task of creating a set of headers and an exhaust that was functional, visually appealing and as symmetrical as possible.
With certain specs for the headers that were specified by the owner/engine builder, we got to work.
We built 4-1 headers, we mirrored the top 2 runners, unfortunately, due to the starter motor location we couldn't replicate the bottom runners without throwing the specs requested.
From that point we did our best to meet the requests.
We landed collectors, cone expander, mandrel bends, vband fl**ges, flex bellows and xpipe essentially opposite each other.
This achieved the perfect symmetry where we could flip the xpipe section and it still lined up with zero alignment issues.
From there we did a split over axle system using to make sure we keep the noise under control.
Again, doing our best to get the same angles, heights, bends, lengths even welding stop/starts to be symmetrical as possible
Every weld tig welded, back purged and made from stainless 304
It tested our patience, skill set and mindset. Though we think we hit the target, let us know what you think!
