When I ordered a set of long tubes for a scat pack from SW they were about 6 weeks out in building them. I was going to order a set of catless mids about 3 weeks ago for my Hellcat and they were 4-5 weeks out on them shipping out. I am guessing they build there exhaust stuff as it gets ordered.
Post on market place for a used set. I am sure somebody has a set of longtubes they are waiting to install and will be motivated to sell their catless downpipes asap.
They look used after 20 minutes of drivetime anyways..... or buy some jba ones.
