Hi. Still no CEL after adding the O2 sensor extension!

@@ktgarage1126 And did you go with 2m cats? And which sensors? Appreciate the information

@@jasonmceeableI went with Kooks high flow cats. Not sure which sensor you refer to? I reuse the 02 sensor. I deleted the NPP Valves and replaced with a simulator from Paragon Performance

Hi. It was an M998

Thanks for the comment! Another viewer also pointed this out a while back! I didn’t have a manual so I was justing figuring things out myself. It would have been easier if I knew about the square hole!

Haha… a lot of people would take that route! I like to do things the hard way

Great choice. We picked this color because it wasn’t available for the 3rd gen back then

I used the weedeater trimmer lines.

Thanks. Yes, 20 in front, 21 in the back. 325mm tires on the back

Hi. Yes, I plan on removing the rear 2 pieces that attaches to the lower control arm and put back on for track use. You still can leave the piece that attaches to the spindle since it is away from the air stream.

Hi. The biggest downside for not having OnStar is losing your GPS. This means you can’t track where your vehicle is anymore. I know that insurance will cover when your vehicle is stolen, but will all the mods I put in, I don’t want to do them all over again with another C8. Yes, all you need to do is unplug the antenna cable and OnStar will no longer work. Not sure about front lift memories, but I think you will lose that as well since it rely on GPS. Any GPS related functions will be lost. I’ll do another followup video when I have sometime. Thanks for the suggestion!

Glad to hear the video is helpful

Not sure about non-Z51, but my Z51 came from the factory with a air vent that's sticking out of the inner fender, pointing at the wheel. It is plumped from the front bumper. The Lower control arm plastic piece I guess help directing the air to the Rotor.

Thanks!

Great plan! You still can install the piece that goes on rear spindle. Just leave out the 2 pieces that mounts to the lower control arm for track use only!

No, it has a 520ci Jon Kasse Boss 9 in it. 800 hp

Thanks for the info! One of the guys suggested adding a screen to the rear duct, I think it’s a good idea. I’ll epoxy it in next time I have the wheels off

If you plan on going 180 mph, these ducts will probably fall off, but I don’t see an issue with everyday driving. They are quite sturdy! I do hard acceleration and stop, but I don’t plan on driving that fast on the freeway

Any debris from street use can be forced into your rotors and cause big problems with the rotors and pads. If you read the owners manual it says for track use ONLY!!!

@@jackm6816I think chances of getting road debris in the ducts are very low. I’ll leave mine on and report back if I have any issues with rotors/pads.

@@jackm6816How about adding mesh screens to the air entry ducts? This will be a personal add-on.

@@mt8073excellent idea. Next time I have the wheels off, I’ll epoxy in some mesh!

Thanks for the comment. I guess the dealer gets to decide whether to install some of it or just left it for the owner to install!

Thanks. These mods are not too aggressive, your C8 still look like a C8. Just a bid different from the pack!

Thanks 👍

Thanks. You will love it!

You don’t need any additional tune. It’s a direct swap!

@@ktgarage1126 that’s great news, what delete tune are you running? Any issues? I heard ez link with ampd is good and sct also

⁠@@JasonShoreI use Ez link with 5 selector switch. Not sure what the name of the tune is but it ran fine with the new turbo. I normally set at 150 gain and it pulls ready hard

I am over 200 miles in with the extender. Still no CEL! It is encouraging….

@@ktgarage1126 Nice! Have you noticed any increase with these? Any new smells? Or hp gain?

It sure does. It stretch to fit very nicely….

Haha. Very funny. Bring whatever you got and see if you can beat us…. And if you drive one those electric abomination, don’t even reply. Sorry, too many beers. Will be nicer to you tomorrow.

You must be a really old dude. Are you sure that’s what your seeing?

Thank you for the interest on the project. It will be very exciting the next few months as I am getting closer to getting the body done and mounting it back to the chassis!

This stretch of highway in Houston is an Autobon for these guys. I take my C8 Corvette out here to test as well!

@@ktgarage1126oh wow you have a sports to nice. Ill sub

I installed both at the same time. However, the hi flow cat is what makes it sound much louder. The cat-back changes the tone, but will not be much louder

@@ktgarage1126 No that’s not true in my case . I have Awe Track exhaust and it sounds insane the cold starts are obnoxious.

@@jasonmceeable are you comparing to a Z51 with valve opened or a standard exhaust? The Z51 with valve fully opened should have similar sound level to the aftermarket exhaust. If you think that’s loud, wait until the hi flow cats goes in. My family in the backyard can hear me from 2 blocks away!

@@ktgarage1126 Wow ! Yeah my cold start is insane and it’s very loud . No I had no z51 just base exhaust. Awe Track is insanely loud just wondering if the cats will add volume.

@@jasonmceeable ya, the hi flow cats will add volume for sure. My cold start will wake up the whole neighborhood. When I leave early in the morning, I had to start with the garage door closed until the rpm goes down! Or all the poor neighbors will be up. It sounds really nice when you go to lower gear to pass someone in the highway

I put on a few hundred miles already. Not CEL! Will update in a few months!

Agreed 100%

Cool idea!

in your dreams

Appreciate it!

Seems like you need to do better research. 400 cells Kooks vs 700 cells stock, which one has better flow and lower back pressure? I can definitely feel the performance gain from the swap. Not to mention the incredible sound. The question is: is it worth the trouble with the CEL? Time will tell if the O2 sensor extension will take care of it. If it took care of the CEL issue, then I say it's a good upgrade. Again, it's not for everyone... and you can form your own opinion. All good....

Thanks for the subscribe. Really appreciate your supports!

Thanks for letting me know. I did not realize that there is a square hole that would fit a ratchet there! That is a better way of putting tension on the belt!

Absolutely! I drove a few miles and CEL is off. Will give guy guys an update in a few months!
