Competition Exhaust Lead times

Hey good folks,

I placed an order for the exhaust a couple days back. Got an email last night that since they’re custom orders they’re out of stock right now and will “likely” ship in 6 weeks. Is this the usual case with them? I just don’t want to be in a situation that they don’t ship for extended periods and I am stuck. They’ve given me a week’s deadline to reconsider at which point they will charge the card
