-Make some Laguna pipes for the Corsa

-People won't like my redneck engineering I did to pass sound at NCM last year. I knew I would be borderline with a supercharged SS with primary cat deletes so i removed the actuators and drilled holes in the bracket to the valve in 2 positions. When i blew sound at the track i dropped the muffler and put self tapping screws into the holes i drilled to keep the valves partially closed. This does not force full stealth mode and the heat issue you see above, but it forced enough flow through the muffler that I had no issues the rest of the weekend.
