Finally completed and installed. My IAP header at long last has a more suitable exhaust system attached to it. The packaging was a little challenging since I wanted dual outlets, a longer segment of pipe beyond the collector, it needed to fit without body mods and be well supported.
The hardest piece to locate was the tight radius 180 right where it connects to the collector. That piece is stainless, since that was all I could locate. Sounds good, even a little quieter than expected. Uses the stock mounting points too! Can't offer an opinion yet on power gains since I ran it only once briefly before the weather turned snowy again, and I still need to tweak MegaSquirt some more.

After paying a top-notch weldor to TIG over my tack-welds, I had to save a few $. My IAP header is ceramic coated though - some 7 years later it still looks great.
