Installed....Rubbed the 2.75" exhaust tubing, so I had to message the tubing with a torch and a big hammer.

Prolly be over a month before I get everything to start building these.. I sent this one to a guy to be test fitted.. Once he puts it in and it fits I'll get the brackets laser cut. They'll prolly be $150-$160 range. And yes I'll build them for the Nnbs as well.

How far back does one need to extend the cross member for a 4WD GMT800? I'm building up my 2002 Yukon getting ready for a 4l80e swap. I thought I read 30mm, but thats only 1 inch and change and seems too short.

Thanks!
