Still better than stock, but proven not to be the same gains as the Louie Ott designed X-Pipe which is what the boys in Utah produce and sell.
Louie put a lot of time and R&D into the exact angle of his X pipe.

The one that 928MS sells is not the same as Louis' design. Fundamentally, yes - in form/execution, no.
Dave assumed the Ott design and then furthered it thru his own means of design, testing, etc.
Look thru historical dyno data "(I have some I can post if requested) and you will see a difference in the Ott and the 928MS x-pipe. Difference being even better gains!

IMO that makes it an even better value for the price they are asking.

The T-bolt clamps that came with the X-pipe didn't seem to hold the cats
connected to the stock exhaust pipe. One came loose on the first test drive.
I still use these to hold the cat to the X-pipe:

That's an H not an X pipe. Have the same one on mine but the crossover is a little more dowstream.

I see you've got the air injection still hooked up in front of the high flow cats. I don't think that's necessary or even wise. Not sure if it does anything but the new cats don't need it to be clean enough to pass emissions inspection.
Clamping might not be an issue though. You've got the pipe sections behind the cats where the 928MS (Lomas) pipes end before the cats.

I dont think anyone would complain if you reposted the dyno data, and where to buy it.
I would not!

928 Motorsports only resell them, they didn't design nor produce the popular X-pipe that several of our vendors resell.
Dave Lomas works at "Motorsports SLC", and Dave further improved Louie's design. Motorsports SLC also designed and produce the cat-back system that Roger recently announced.
Anyway.. carry on..
