I am going to install my Corsa High Flow Cats soon. I have a HTC so I know there is a little more involved to the install but I'm getting myself mentally prepared for it. Also doing a ported intake manifold, Soler 91MM throttle body and a blue attack filter at the same time. If there is anyone in the greater indianapolis area that wants to partake in the installation all help appreciated LOL
If you need any install advice call or text me 201-575-0861. I've done it all from installing them to breaking the studs off the cats and replacing them 🤣

Like your plans Soler 91MM TB / Ported Intake Manifold......BUT here's a good suggestion. Don't pass on adding the Soler Throttle Controller!
This mod completely wakes up the C8 dead pedal. Probably the poorest response from any oem I have ever owned. This TB has 43 settings and is likely best bang for the buck out there.
If a "louder" exhaust is the primary goal, may want to check this out... a very popular item for C6's with the performance exhaust option, I had one on my C6 and it delivered the desired sound without making any mods to the stock system and it provided the option to turn the louder option on and off as needed.

Already have the Soler Controller installed. Thanks

If you have any questions please reach out. I just did everything you are doing in the past few months so it's all fresh in my old *** brain.

On the c8, how can you mke it a little louder. Wanted to add a magna flow cat back muffler, but understand that the rear bumper must be removed. Anyone know of another way to change the mufflers?

I always see people's heads turning to look at the car before I am even in visual range. And, my wife says she can hear me coming home when I turn into our street if she happens to be outside.
For those of you who have DIY your catback, did you take the wheels off? I think all the videos I've seen of installs remove the wheel. Just wondering is it needed or just makes the job easier.

No need to take the wheels off as long as you have tiny tools to remove the t15 torx screws from the wheel arches. No need to lift the car either.

Awesome, thanks. I think my friend and I are going to attempt to replace his exhuast in his garage. He is fairly mechaniclly inclined, I am not. I watch a video and think "that seems easy" and then end up in some trouble. Plenty of times on my camaro I had to put it back together and take it to a shop.

IMO your biggest challenge will be getting to the stud bolt way up in the fender. A right angle tool is very helpful here.
Have plenty of extensions and flexy joints on hand too.
Lastly, whatever you do don't cross thread the bolts that screw in to the studs on the cats. ☠️
IMO HFC are the way to go. The sound and pitch is so much more aggressive. Every aspect of the sound is better. Idle, mild throttle, WOT, decel all way more aggressive.
You may chase CEL with cats though. It can be solved but either get a 600 CEL cat or run mini cats if you don't want CEL. Below is my car with Stainless Works 400 Cell GSport Cats and 2M Heat Blankets.
