I can tell you with those mods and the right pully selection, add DSX aux fuel pump and proper ECU tuning, the car should make around 720whp.

Tuning is everything and I would only trust mine with a few people.

Ahh ok then. What I said before still applies, 30whp or so with headers and high flow cats.

I just realized you have a CT4 Blackwing so your power gains from headers are going to be a bit lower than what I quoted since I thought you had a CT5 Blackwing, my bad. You can probably expect 20whp from headers and high flow cats. I would reach out to @WONT TAP (Tapout Tuning) and get their...

He gained 10whp going from high flow cats to off-road pipes but this was on a car that made over 1000whp. Here's the thread. https://www.cadillacvnet.com/forums/threads/ct5-bw-ported-2650-1010whp.5800/page-2

You misunderstood. You would gain 30whp going with headers and high flow cats compared to the stock manifolds and stock cats. The guy that gained 8whp had over 1000whp so unless you plan to mod yours to that level, you would see almost nothing swapping out the high flow cats for off-road pipes.

With green cats (high flow cats), there's almost no difference between a high flow cat and straight pipe other than cost. There's another member here that has Blackwing that makes over 1000whp, he removed his cats and gained about 8whp. That's nothing on a car that makes over 1000whp and most...

Many people have installed them without a CEL, I can't guarantee it though. Tune is not required.

Well, if it helps, the Kooks will add 30whp, the Corsa catback will add none. Sound is a very subjective thing so no one can tell you what sounds best to your ears. Kooks headers and green cats will likely void your warranty at most dealers, although its possible you might find one that won't...

I own a 2024 CT5 Blackwing and a 2024 CT4 Blackwing, both with 10k miles on them. My CT5 Blackwing is still on the original batteries, my CT4 Blackwing was showing a low battery alert with both key fobs when I bought it last week. I swapped the batteries in both key fobs for the CT4 Blackwing...

I own a 2024 CT5-V Blackwing A10 and a 2024 CT4-V Blackwing M6 and I wouldn't have it any other way. I just don't feel like the CT4 Blackwing would be as much fun to drive without a manual and I don't think the CT5 Blackwing would be able to get the power to the ground with a manual as well as...

Good info if I ever decide to add headers to mine. I've only used Kooks in the past and have no complaints.

Now that, I can absolutely guarantee will happen.

Used Blackwings are NOT selling above MSRP. You may seem some listed for sale above MSRP but they aren't selling. The overwhelming majority of used Blackwings are currently advertised and selling UNDER MSRP right now. You're going to be shocked on the value of any of these special edition...
