Default Agency Power headers?

Anyone has them installed ?
I like the design, like PFADT, it's perfect for my stock engine.
I don't really see the use for very long primary for me...they sound weird, lot of extra noises in the car, also from my experience I don't need the extra torque low in the rpms, the vette has plenty of that...I would like some extra high power.

I belive they bolt on to the stock x-pipe wich is a plus, if you want to keep the cats on....the stock x-pipe is actually a very good design with metallic cats.

You get what you pay for. If you want quality, go with Kooks or ARH! Agency is a budget brand anyway.

Well, Joe @ Cordes Performance just installed my Agency Power headers today.

Review;

Fitment: He said the fitment is horrible. Having to bend a plug out of the way because it would be on one of the pipes.

Sound: I absolutely love how it sounds. No drone at high speeds in 6th gear. Loud when you want it, quiet when you're not accelerating.

Performance: I ended up getting the car tuned afterwards and got 418 HP & 426TQ to the wheels. Not bad.. From what i understand and what I was told, the stock C7 Stingray makes about 380-385HP/TQ Stock to the wheels.


All in all, not a bad result for the price of the Agency Power headers and X-pipe. One important thing to note, if you're planning to install the headers yourself, maybe spend the extra money for the Kooks/ARH setup instead. That's only based on what Joe told me, and he does this stuff for a living so I'll take his word for it.

Never understood why one would spend 60-90K on a vehicle then put budget parts on/in it.

What other mods do you have? Your dyno seems kind of weak to be honest. Are you an A8? Anyway, more power to you! I'd never install budget parts on my C7 but different strokes for different folks!

His numbers are right on par for a manual c7 no cold air in AZ on our junk 91.
