Best C7 headers for component clearance and road course use?
C7 engine bay is tight compared to my C5s and the OEM exhaust has a lot of heat shielding. Obviously they added it for a reason.
Already have a Corsa X-pipe.
Can I do American Racing mid-length with cats and get away with no tune?

Dont bother with MID length, absolutely no gain , many posts about this , they dont scavenge any better than the stock manifolds

Here is a post of a Stingray we did ARH catted mid lengths, X pipe, and no tune. Before and after same day on our dyno. Great combination if you already have the x pipe and dont want to tune with longtubes.

Again... I don't want power. I want my engine warranty in place and easier service of the exhaust. The factory cat pipes are a PITA to work on.

Yep , I am asking the same question , in closed loop the fuel trims can make up the difference in the extra fuel that is needed but I have to believe when the ECM goes into open loop it has to be on the lean side , maybe not …

I know that the Warranty Act says that they have to prove that the headers caused an issue but remember ...its all up to the dealer and GM on what they cover .
My dealer is a high performance dealer and knows me well from my C6 days on which I did install a headers , CAI and a tune ...
I drove my C6 for 67 thousand happy really fast miles lol , then I buy my C7 A8 and had to have the motor replaced at 30,000 because it dropped a valve , just driving down the highway at 70 MPH minding my own business , its the one time in my whole life that I was happy that I did not have any MODS done even though I have been chomping at the bit to put a CAI , headers and a tune on it ….and just in case anybody was wondering , the first thing they checked was the tune file …..
I am going to wait till I get closer to the end of my warranty before I start bolting things on … just to much expensive stuff that can go wrong , plus the car is already an 11 second car on street tires

Has anybody tried to get engine warranty work done with headers on the car with no tune … I am thinking that you might run into an issue when they see that , tune or no tune ...and forget anything that has to do with Emissions Warranty ….
