they are good looking pipes, i'll grant you that, but from the looks of it they are just hanging from the flange bolts. definately have to double nut them and maybe use double gaskets.
Those are made from MLBCUSTOMS.COM they are cool, but good look getting a hold of them. I tried for 6 weeks to get someone to reply to my calls and emails and no one ever did. So I gave my business to stainlesscreations. They build the pipe that you want and get it to you fast. Oh and did i mention LOUD!!!!!!
I looked at those as well...
Loved the the way they looked, but heard a lot of problems keeping the heat shields from rattling and broken studs.
They are also 1.75" all the way through, which may be too restrictive with all the bends ?
