These have new gaskets, studs, nuts, washers and a recent polish. The snails have the step down thats 3", 3 1/2" or you can put a small piece of 3 1/2" hose on end to get 4" exhaust. The snails are also double drilled for mount variations. If your looking to upgrade to a non leaking pair of logs....these are the ones. I have seen these go for over 400 on ebay in bad shape. I have a set on my ford now and completly satisfied. Had the other style with just a small flange to mount and always leaking. I was going to keep as back up pair then decided to sell. I will be selling these on ebay soon but thought I would give SoCal a shot first. I want $ 500.00 firm plus ship
