Manufacturer and Amazon failed me, didn't deliver order after 10 months and cancelled just now! 7 months ago I called to either cancel or get the item as well, and the Amazon rep LIED to me saying they were getting the mufflers back in stock already so I should just wait... nothing. Destroyed my project and now increasing pricing for me as I could have gotten it and other parts in the order elsewhere nearly 11 months earlier! (now it's winter)
