Has On3 gotten any better? Ive seen a few coyote guys run them.
I remember when they first came on the seen and it was garbage. Chinese SS that would rust and nothing would fit.
Just due to those facts I wouldn't even look at them.
I've used both On3 and CG fabrication for turbo kits. Lets just say the On3 was significantly cheaper but the quality of the weld were better. The CG headers i received were warped so bad they wound never work. I sent them back and got a refund. With the refund money i purchased the complete On3 hot side minus turbo. The quality was great way better than expected. i test fix everything and had no problems with fitment. I later removed this as it was a single setup and i wanted twins. So i went back to CG and ordered another set of headers. These ones were good. they were straight but the welds weren't the best looking. Overall they did work and i was happy but just thought the welds could have been better.
With all this being said there is nothing wrong with an On3 kit. if money is tight i would go that route. if money isn't an issue i would recommend a custom turbo kit. if you have buddy that can weld it might almost be cheaper and you can make the kit fit your needs and mods! Thats the route i took. bought CG headers and had a custom kit made to fit twin 6766s
I wish cg fab would just offer a complete kit. You have to finish off the kit. It will cost me just as much as getting a complete kit from another company.
