For those that are using the Mufflex pipe, how was the fit? Was it any where close to a bolt on install? I need a pipe to connect the JetHot LTs to the Borla cat-back and I'm not having any luck finding a shop to make one for me. I've heard bad things about the Mufflex pipe but that was a couple of years ago so I am wondering if they have changed it to fit better?
TIA

I've been through this in detail with the owner of Mufflex. The problems that occured a couple years ago were the result of poor quality control on the Hooker end, when they transferred their header fabrication to Mexico. People were getting headers with collectors sticking out every which way, and the 3-bolt flanges were "upside down" at times. Mufflex builds the Y-pipes in a jig... there are no variations in the dimensions of the pipe they produce. The problem was in the dimensional variations Hooker was getting with the Mexican plant startup.
In order to cope with the extremes of dimensions on the Hookers, Mufflex changed the design to put an additional piece on the drivers side tube, to allow it to be rotated to match the width problems with the Hookers, and started using a "loose" 3-bolt flange to allow the new piece to rotate, and accomodate the mismatched Hooker flange alignment.
