This is our final stage for our LS3.

Today we installed the complete ARH catted header system to compare to our other header setup...as expected we gained.

Very nice Andy ... !!

Are you going to give it a tune and post more numbers?

Yeah probably in a week or so.....If you know what I mean!

We just want to show people that with proper choices of camshaft and exhaust that stock tuning can work as well as stock airbox and filter can work.

Remember what I originally said,you could take this car into any dealership and they would never know that it has a cam in it,It does not throw any codes with stock cats and exhaust...This means you could actually put the stock cats and manifolds back in (2hrs max) and keep your corsa,gm,magnaflow, etc catback and the possibility of voided warranty or denied warranty are very slim....No ecm tune means no red flags.

It is just an option that we believe needs to be available.We have alot of options available....ALOT!

Good deal, I know that will mean a lot to people. It is great that there are companies out there like yours that is doing this and showing the gains associated with mods like this.

The before and after torque curve shapes don't show any significant valve timing change. So, the gain must be from the headers. Suspect the gain is from leaning that will mostly go away when the LTFTs catch up. A full throttle tune to 12.8 AFR and NO hardware changes would be my choice.

Airfuel only changed slightly,11.9 at peak power and 11.5 I think was the stock air fuel,COT probably kicked in on the stock run considering I just came off the street with it on the initial dyno.

Cam is 207/23x -5xx 5xx 120
