Question: does the shape of headers have an effect on performance? Those seem very twisty compared to others, so I'm just curious. Can't wait to hear it!
Keep us posted on how the stock ecu handles the changed a/f ratio with the primary o2 bungs being so high up on specific runners rather than on the collectors. I'm curious to see if it leans things out a bit.

Oh yea, that's interesting. The A/F sensors only monitor 4&8 with this design. I'm curious to know how that effects things as well.
The fitting they use to pull the rear o2 out of the exhaust stream is also interesting. No electronic simulators I'm guessing? Is there a small catalyst in those fittings?
Gorgeous! When can I expect to look out for the PPE's to pop up for sale? Your old Borla exhaust needs some company .
In the next week or two lol

If you got ECU from Nigel + Novel header it's the perfect mods that i wish.
That is the plan after the header install!

Thanks, I too saw that post on instagram as well.

Yes, smoother flow as the exhaust gases exit. In theory should perform better than the PPEs or Sikky.

Congrats btw, those are some beautiful headers.
Thanks guys, I will keep you guys posted I looked at that and curious to see if it actually does have an effect. I'll have to take a look at the angled adapter but it looked like it was a mechanical o2 fix, I didn't see a catalyst in it.
