I do rear mounts.....and front mounts.....
The only reason for a rear mount is packaging......hence the 4 th gen and rear mounts.
The 5th gen has just enough room up front ......Im just finishing up my jigs now. Ill probably have them done in about 3 weeks. Its a tight fit to do it right.

The reason that merge is truly awful is flow. you do not want one pipe turning into the other, you want two strait pipes intersecting, what you have now is sort of like a lower case "h" which will cause a huge amount of turbulence at the merge itself and impede flow like its going out of style. a V shaped merge with as gentle an angle as possible is best.
from seeing other people experience I will estimate you get full spool roughly 1000 rpms later than you want, and probably lose a good 30 whp with the merge you have.
its amazing to think it will have that much effect, but the bottom line is IT WILL. You have great fab skillz, weld the braces back on, cut off that merge, use the same whole and make it better. sweet build, were here to help, lets see some pics of the car too

I'm going to take your advice and rebrace the pipes and fabricate a different merge.
See below: What do you guys think of this? I'm trying to reduce the number of bends with the current configuration and this is what I came up with. Here's my awesome MS Paint skills. lol
I'm still going to run with the rear mount, but before I start cutting I wanted to get the board's opinion.
Thanks,
Vince

a flowmaster merge is nice, but a simpler bet is just flip that bend thats welded on there. (so that the inside radius is facing the chop saw side.), weld another piece of 2.5" onto that, maybe 3-4" long.

see how that is? simple, cheap. obviously you'll only have a 2 into 1, with a 90* bend on one end, 2.5 into a 3.
