I am thinking about adding ARH long tube headers to my 2016 C7 that has the factory NPP performance exhaust. My question is, will there be any fit/ installation problem with my factory exhaust? Wihat, if any, modifications will be needed? I love this car, and don't want to mess anything up just to gain a few more horsepower.

Thanks in advance for your input

I just installed mine. ARH 1 7/8 and offroad x pipe netted to factory NPP. Very easy install according to the installer, fit was perfect.

No issues whatsoever, car sounds so good now.

My install of AR 1 7/8s headers with their x pipe matched right up. No issues at all. Good luck and they sound amazing.

When my warranty runs out, I'll put ARH LTs on my car. I already have the Borla Off road X-Pipe so it's a matter of the headers and a slight tune to make things mesh. All CATs gone and the NPP makes a good sound when you open the NPP with a M2W switch. Closed, wife is happy, open, I'm happy. Oh the joy!

Man a piece of cake if you will be doing it your self. LG LT headers here with 3 inch mid pipe and Borla ATAK NPP on the car...I do all my work on the car now it was really easy & not one problem.

Plus to me the ARH headers is like the LG stuff top of the line parts. Robert

goes right on, if you have any tech questions or would like pricing on a set just let me know. We have ARH and Kooks in stock.

I have a question. How about the "shorties" with cats and do I need a new tune?

done them, car did not throw any codes at all.

Will the car pass an annual OBDII scan for emissions testing, after?
