I believe I did read 2 as well email 3 files, if need it will do it again

The third file was a .efx file which we don't need. It will be a .ctz file just like the engine tune file you sent. Your data log you sent is the .efi file.

I don’t have FB and all the videos he has posted play fine for me...maybe it’s your browser?



Having owned both I would definitively conclude you can’t go wrong either way, one isn’t better than the other....think of it as like choosing between Lamborghini or Ferrari, there’s no wrong answer, neither has a clear cut advantage over the other

here are some side by side pics I took for comparison:

Top kooks 1 3/4" // Bottom ARH 1 3/4" (both for NNBS trucks and SUVs)

If anything I might give the slight design edge to ARH as you can see below on the passenger side header (1st pic) with the Kooks you have to route a starter ground wire (requires removing 1 bolt) through the primaries where as with the ARH design you never have to touch this wire and it already clears underneath the header, but then again when it comes to the y pipe design I prefer the Kooks Y as they offer a Y Pipe specific to the year model since they changed the cat-back connection between 07-08 and 09-14...Kooks offers 2 different Y Pipes where as ARH Y Pipe just comes pre fit for 07/08 and includes an adapter for the later years

I like the comparison , are the adapters know to leak? I have ordered a set of ARH with the high flow cats and will be running stock muffler and res on a 6.2

OP, looking forward to see how this turns out and the power it puts down.

AirAid intake installation update, so far happy with the product, only complain would be lack of clamps for PVC breather line which I have add it (not really sure if its that important).

I'm personally not a fan of the boots but the ACCEL Extreme 9000 Ceramic Spark Plug Wire #9002C is what I decided to run... I made them to length but the ones you posted look plenty long, mine are a touch shorter.


They both are great headers and you can't go wrong with either... I will say the build/fit quality on the Kooks are amazing. Details like in this post below are why I love them. My truck sounds like a freaking beast, no video or sound clip does it justice.

it looks like they will work AC Delco OEM vs Accel length.

No, I never had any issues with anything leaking. When installing them I would just get everything hand tight and once you have the whole system installed and you are happy with all the clearances go back and snug everything down. Also I recommend going with OEM MLS exhaust manifold gaskets.

AC Delco for sure... As I mentioned, you may want 1 stage colder though and iridium doesn't do well for high cylinder pressure. Great for a 100k mile plug though

*start with an AC Delco LSA plug from a CTSv or ZL1 Camaro if you want OEM

it a big deal to find copper spark plugs these days.

I know lol, I don't know why. Problem is the idiots and software they use at the parts store won't look up anything at all without a vehicle description. The days of easy cross-referencing and finding spare parts for custom stuff easily is over. Any time I look for a part for my truck I have them look up a CTS V or ZL1. Try the plug number I gave you. It's 1 stage colder than a stock LSA (good for up to 15psi) and it's a nice OEM style copper plug. Copper is the way to go if you're over 10psi. Cylinder pressure makes those iridium plug harder to fire. Just look how tiny the surface area is on the electrode compared to a copper one. It's a tiny pin versus .100"-.125" on the copper. Your ignition will run better under high boost and cylinder pressures.

not sure what number are you talking about? could you please post it again
