The other thing that needs to be noted (if it was noted earlier in this thread sorry I didn't check) is that the Magnaflow kits are from the header collector back, so if you are running manifolds you will have to get pipes from the manifolds to the magnaflow pipes, not a big deal, but something to be aware of. Also the stainless pipe from magna flow does blue, mine did on the cuda.
As far as PG Classic goes and their prices, whatch their ebay store. Around this time of year every year that I have shopped with them so far they do like an inventory blow out and list a bunch of new items on ebay with no reserve and start at a dollar. I have gotten some great deals that way as much as 75% off the retail price.
