So, I finished mine.
Interior sound video:
Exterior and interior (I just cleaned it, completely irrelevant to intake, but...) photos:
Sample photo:
I'd give it a 9/10. Sound beastly, and, according to butt-dyno, adds power.
I used a 45 degree first bend to keep it as far away from the intake manifold and block as possible, to keep intake temps low. I used the two 90s separated with a straight piece to improve high speed flow at high RPM by reducing the sharp 180 I've seen on others.
All told, I'd say it was like $150 CDN, and that includes drill bits, vacuum bungs, vacuum hoses, hose clamps, piping, connectors and everything else I needed.
And, best part: No MIL/CEL, no stalls, no hesitation, and it's quieter at low RPM...
