6"^Dia. Left Diablo Reduced Expanded Chrome Exhaust Stack

⚠ Please Note: The pandemic brought the American steel industry to its knees last spring, forcing manufacturers to shut down production as they struggled to survive the imploding economy. But as the recovery got underway, mills were slow to resume production, and that created a massive steel shortage.

Domestic steel mills that idled furnaces last year amid fears of a prolonged pandemic-induced economic downturn have been slow in ramping up production, despite a recovery in demand for cars and trucks, appliances, and other steel products.

The delays in stack production can be significant and it is possible those delays might cause an extended lead time of 5 to possibly as much as 6 weeks for 5", 7" and 8" stacks. 6" stacks seem to have been impacted the hardest with lead time that could be as high as 8 weeks.


We do apologize and hope this will not stress you. We will keep a close eye on production.
