I haven't seem to have had the "growing" issues as much as some of you.....I am sure at some point I will have to deal with it though.
All of our stuff runs flex joints and the "snapper" grommets that were seen in the pics a bit back. But I mount them bolted to another bracket.
Also, I have put some serious heat into the exhaust via super and turbo charging, and I have yet to have my stainless stuff get grey like the pic of Blu Ballz exhaust.....I know he tracks it, but the crossover section there is a bit back from the collectors....ours only goes gold/purple. Is this just exterior contamination like oil that makes it go overheat grey like that? Maybe that has to do with the cracking.
I have use fusion on stainless exhaust joints too, it looks amazing. I havent been experiencing the sugaring issues that much, I have only purges on header tubes, not our exhaust systems.
What tungstens are you guys using? On 16 gauge stainless I am only running 30 amps max to get a nice bead. I have never had to put 60 amp into stainless exhaust unless I am adding an 1/8 inch thick bracket or muffler/flex joint lap welds. I guess its all in the welder operator!
Good info in here. I do believe you on the exhaust growing Greg, just haven't experienced it myself.
