Templar X Exhaust De-Cat

[tknj99]

Planning to de-cat the Templar X exhaust.. fam got me a Harbor Freight Flux welder but it says not for stainless steel.. im a total newb with regard to welding and would have to do some research before even using it but before i waste time on it and cause a potential mess, can anyone confirm whether it would or would not work to weld the exhaust back together after its uncorked, thanks
