Default Long tubes and Y Pipe for 6 speeds?

Did that one company ever come out with a y pipe that fits the 6 speed 2007+ trucks?

I remember there was a thread on it, but it appears to be gone??

Thanks

Pacesetter makes 1 7/8 long tubes for NNBS now, and they offer a Y pipe. Does theirs not fit the 6 speed? I thought all of the 6.2s came with 6 speeds.

I have 1 7/8 speed engineering longtubes with their ORY pipe and they fit great on my 6.2 awd 6speed denali. Just install new motor mounts and install the starter before you mount the headers.

I have cheap OBX headers and their Y pipe on my denali. I didn't have any problem fitting the Y pipe with my 6 speed.

So just out of curiousity does Speed Engineering offer a Y pipe that bolts to a 6.2 catback or are you stuck cutting and welding? Doesn't look like they do as per their website.

It should, I recently got my headers and they came with the ball flange for the 5.3 style and the 2 bolt flange that I assume is for the 6.2 trucks.
