That is Hilarious! lmao!!
I've never seen that before.
One of the biggest issues I had making the 3" mandrel S/V's was trying to find a Good quality cast 3" 90 to weld to. Even the best ones I could find with the least porosity were Brutal to weld on. Always splatter and tons of clean-up after and all in between the process.
That, and making/ modding the 2 1/2" S/V flange and donut to 3" added to things as well + need a 2 1/2" S/V core to use.
There was a time early on that I looked into having them cast from a mold, but start up cost would have been 10,000+ USD and I would have had to do a massive group buy with money down and I just don't like doing that. Too many factors that are out of your hands and no matter who fault any issues are, you will always look like the "bad guy".
So I tried to source out some pieces over the last several years and even tried to have one of our own community machinists join the battle to no avail
Finally sourced a true 3" flange and made a "prototype" that I was quite happy with. Was going to swap out the cast for a Thick SS piece but ID did not jive. I really felt that IF I could spend more $'s on better quality stuff to weld out, it would pay off with a much easier piece to make. Finally tried a 3" mild steel Thick walled piece and it welded much better. Finished the prototype and it is on Martin's wagon right now.
Shortly after finishing I checked stock on the 3" flange and there were none and haven't been any available since lol
Really sucks that the ATP piece is no longer available
The only reason I even made my S/V available in the first place was because there was nothing else out there for the individual that just wants to bolt on a performance piece like this without having to "build" a 3" mandrel system himself. When the ATP piece came out, I was relieved because now there was another option that the community could go for the same level of performance.
Maybe a group buy would bring ATP Back on the playing field?
