I recently ordered an Invidia N1 exhaust system from autoplicity and to be honest I was concerned at first my order was not shipped for 2 days, I know I was just very impatient. I'm not sure how their business works but 2 days of processing? I emailed their shipping department and got an email back explaining everything and it also said I would get an email today or the next day and sure enough I did! Had the lowest price for the part I was looking for. Also all the good reviews just made me want to order from this company plus the good prices you can't go wrong.
