I've been nothing but impressed with the customer service, product, and quality of ARH headers. The fact that they make killer power is a nice bonus too.
I can text Steve@ARH and get a response back ASAP. Great guy to deal with. Nick the owner is great too. Plus american made with american sourced parts.

I'm honestly surprised you didn't wait to install the headers before replacing the NPP.
It's an awesome combination with a factory cutout that's loud as hell with headers. But, to each their own.

Thanks to all for the comments and suggestions. After a series of discussions with Roger Preston from Horsepower Sales I've decided to go with ARH headers. Still discussing whether to go 1 3/8 or 1 7/8. It will depend on the size of the cam. Roger and Jeremy are gathering info on this mod.
As was noted in one of my earlier posts, my C6 was a monster on and off the 1/4 mile. That beast was built by Horsepower Sales and they liked their work so much, they bought my C6 and converted it from a straight line racer to a road rally speedster.

From what I've gathered from ARH, the 1-3/4" still have an advantage up through the 500+whp area. Once you're in blower territory, the 1-7/8" take over.
I actually ordered and planned on using 1-3/4" with my blower, but just switched over to the 1-7/8" on their recommendation.

Im on very thin ice around here right now due to my opinions so I am going to simply agree with your statement and let people know to research your purchase carefully before spending your money. If you are in doubt about what system to purchase I would recommend the OP contact Doug@ECS or Ron@Vengeance for further help. Neither of them will steer you wrong or push you to a inferior product. Togther they have created the most powerful C7 the world has yet to see, I dont think you can find a better group of guys to take advice from.

I'm not sure I agree with that fully - the independent tests here have all shown ARH being well ahead of Kooks - both the 1-3/4" and 1-7/8" on both stock and cammed cars.

Let’s just say we are still in “Magic” dyno times LOL. Tune only numbers (no mods) exceeding header x, y, z… At this point I’d take most results with a grain of salt, because it’s a big advertising push on CF for business…

I should have posted this here, but I had PMed it and forgotten.
The gains and differences between both after tuning is most likely negligible. Not sure, though.
Redline also compared the ARH 1-3/4" to the 1-7/8" and then to the Kooks 1-7/8" on a stock C7. That was a better indicator for most people than cam testing.

Hat's off to Ron and his team at Vengence for putting together a comprehensive test of a few C7 header designs. We where doing our own testing at the same time and finally got a chance to test out ARH's 1.75" LT as well....
ALL tests where done with a stock GM calibration, 195-210 coolant temps and 180-200 degree oil temps. Three pulls where made with each header and the runs shown where the middle of each.
The 1.75" header was quite impressive on this 100 percent stock engine. Will be interesting when Ron tries these on his head/cam build and ours on a supercharged engine. Both the 1.75 and 1.875" made the same power over 4800 rpms so it will be interesting to see.
My quick rip around the business park most certainly felt the increase in the punch zone....

LMR has my C7 right now. They are putting headers, cam & an ESC SC. I know they will do a good job. If I get 740hp and I could have gotten 755hp. I don't think I could tell a difference.
