Thanks KING, I just edited my comment. I agree, wish I would have known that these cats are not rated for anything over stock power levels :( I dont have high hopes for the sound changes dropping the cats. Quick question; is it safe to assume that the car will adjust after removing the cats? or do I need to adjust my tune at all?

Well, I have put a few miles on the car with no cats and well... YUCK.
The tone has shifted away from deep, I lost some of the cool popping, and I really didnt want the extra volume... but most of all, the SMELL is terrible. I think I will be ordering some GESI Gen2 4" HO cats rated at 350-500 per cat... or the 4.5" UHO rated for 850 per cat... Anyone try the 4.5" yet?

Thats a great idea... I use V-bands on my system also. I was also worried about excessive back pressure with the small cats, and (3) mufflers. Would be cool if everything was removable, so we could get some back to back to back dyno testing.... hmmmmm

I wouldn’t do anything less than the 4.5” ones on a boosted car FYI.

Hennessey put Green cats on mine at 700whp. I think they lived at that level but I had to fish them out of my AB when I jumped up to 800. I see GSport sells a 1200hp version now.

Assuming you have 3" tubing... this is what you need. A proper performance muffler shop will have what you need. https://www.summitracing.com/parts/v...BoC4tkQAvD_BwE

Just ordered them! I'll make sure my muffler shop gives me a matching set of off road pipes to swap out when I dyno... etc...

For street use only, I don’t think I could melt them if I wanted to lol. Just can’t get into the car long enough at this power level without going to jail.

Question that is bit of thread hijack. On my 2019 ZLE with 16k miles, it is all stock but a Weapon X catback (sec cat delete) tune and Weapon X intercooler. I have already blown the stock cats once, replaced with another stock set and am looking to the future. The car is 99% road course use and I'd like to end up at 650 wheel - ported stock blower, LTs and I would prefer to keep cats on it. The current catback is horrendous...the drone is driving me insane, can I find a used stock catback to go back on and use it with the above mods?
Ken
