Don't think I've posted this, I'm not even certain I've looked at it before, but we've been asked a few times about how much power is the car making now compared to when it was stock.
Run1 Stock, Run 2 with Vektor Headers coated and Cobb OTS Stage 1 map, Run 3 with all of Run 2 plus modified OEM exhaust (valve relocation). Usually you see plots with only the MAX values shown, but I added the Average values as well, as it tends to give you a better idea of what to expect as a whole across the plot.

I read the MotoIQ article and had one question. In the comparison photo of these to the stock manifolds, the ports on these appear noticeably smaller than stock. Can you advise on that please?

Our flange has a distinct edge. It's also the sized correctly to the head port. Comparing ours to OEM you will also notice the OEM ports vary in size (cross sectional opening) as well as how centered they are on the actual port. These are all due to manufacturing deviations from the process that's used to assemble them. The CNC design we use assures identical port geometry as well as location.

Could you provide some details of what was done here please? Very interested!

So we modified our OEM exhaust by relocating the 'sport' valve directly after the cat, giving a straight shot to the tip.

I would guess the turbos, more than the cats. By my calcs the OEM cats have a bit more to go before they are the dominant bottleneck. I suspect the tiny turbos are close to tapped out. External wastegates should free up a good bit of power as it lowers pre-turbo backpressure while maintaining target boost

Coated headers IN STOCK! The lead-time for Swain Tech Multi-Layered Ceramic Coating is often times 4 weeks or more due to the nature of applying many coatings over weeks-time. Trying to stay ahead of the curve we sent some extras along with the last batch
