AHH finally after almost 2 months of waiting, greddy Sp catback is no longer on back order!!! I got workd from greddy warehouse they were receiving the first of many shipments of the SP cat's (for all cars) and this first shipment included 3 for 4th gen maxima!! and guess what! One was mine...YAY YAY!!!! I have confirmation is has been shipped from greddy should be here tuesday or wednesday. Can't f'in wait. As I always do, since im a newb I will post comments and personal review once installed, which should be about the same time I get my Gen2 carbon fiber altezzas from procarparts.com, so maybe it will be a 2 in 1 deal.
