All GPR exhausts are hand made to order in their Milan factory. Delivery times vary on a seasonal basis and can be affected by material availability and other factors beyond our control. Full systems will nearly always take longer than slip-on options and in most cases will take 4-8 weeks to get to you. Most slip-ons will take 2-6 weeks. If you need something faster that this timescale then please contact us prior to ordering and we will get the very latest information from the factory. But please note, that information will only be accurate for a day or two.
