Thanks, I just cut the tabs off. In December I am going to get the wald lip molded, shaved and have the badge holder filled in flush. Much like Devin and Cary's ISF

This isn't your typical Sikky vs. PPE header thread. I switched from Sikky headers to PPE headers and all I can say is I feel more response/power with the PPE headers and they looked A LOT better.

We did have an issue with the CEL P0607 and P0138 kept popping up we were puzzled. The next day after 6 hours of double checking the module and the connections Ryan found out that two of the pins in the o2 harness extension were reversed. After we flipped them I still had a few CELs pop up but then they all went away on my drive around the block. So if you run into this issue make sure the o2 harness extension is wired correctly!

Modifications were the same before and after the install except for the headers. Only notable power modifications are Sikky/PPE headers and a Borla Exhaust with the cats and resonator removed. All runs were done in with sport mode and in 6th . The Mustang dyno was clearly having some issues when we ran the post install setup with PPEs as we saw gains of up to ~170whp. Rob (owner of Vivid Racing) was surprised with even the output on Sikky headers as it performed better than his C63 . They re-calibrated the dyno and it still consistently ran ~500whp. I am going back again once they have someone take a look at the dyno. So stay tuned for more accurate results! 

UPDATE: Results have been posted and are accurate. Now you can see the power and quality difference when tested on the same car, conditions, mods and etc.
