Installation details;
- Crawl under car and mock up location - mark with sharpie.
- Remove DP, use angle grinder to open up a gaping triangular hole
- Faff about cleaning and figuring out a ghetto way to backpurge without dual regulators.
- Melt stuff together. (A welder I am not)
Lessons learned; positioning is so so important. If you aren't comfortable and stable, it's going to look like dogshit.
And if you're screwing up with your tempo and things start getting hella hot, just stop, and be patient letting the part cool before continuing.
