V-Series Cadillac(s)?
2022 CT4-V BW
Greetings all,
I've been living with the Corsa cat-back exhaust since early October on my manual transmission CT4 BW and it's time for a review! I attended the Corsa tour arranged through our Columbus Cadillac V-Club chapter and with the help of Tapout Tuning. Corsa needed one more car for a pre-production test fit, so I volunteered to head up to Corsa early and came home with an exhaust. Thanks @MikeGuy993 and @WONT TAP ! Carl Lemmerman Jr., (Corsa Produce Manager) was an awesome host and it was inspiring to see the combination of high-tech engineering and old-school handcrafted quality. When you see the work involved, you understand the pricing. Fellow V-Club member @Dirkbg already posted some outstanding pictures which I'll link below.

Let me start with the main questions on the top of everyone's mind:
1. Does it sound like a VQ Nissan? H#ll no.
2. Does it sound like a Charger V6 with a broken exhaust? No!
3. Will it change my Blackwing driving experience? Yes! You actually hear the engine, and it shows how synthetic the sound is stock. It's transformative to the driving experience, providing a mix of race car V6 noise and some bass rumble. Unique sound goes toe-to-toe with V8 sounds. You'll start ripping downshifts just to hear and feel the noise. Every small change in throttle position causes a change in sound so part throttle daily driving is way more rewarding. It's gives back a bit of what we used to enjoy with NA-motor induction noise. And cold start is epic! Valves closed, it's slightly quieter than stock and a better cruiser for it. Valves open, it is loud outside on throttle, so unlike stock you may want to think about your impact on your neighbors. If you bought this car as an M3 or Camaro-in-a-tux competitor sports car, you'll love it. If you bought it as a fast Cadillac, M340 competitor daily driver you may find it too much. If you've heard a Corsa extreme Camaro SS exhaust, knock the volume back a perceived 20% and you are in the ballpark for this product.

I've attached two sound clips from inside my car, cell phone mic. I think they are directionally accurate about the sound quality, but they capture none of the intensity. The clips on Tapout Tuning's webpage, linked below, accurately capture the external difference in sound quality between Corsa and stock but not the difference in volume/intensity. You also start to hear turbo noises on the outside, not as much as with downpipes, but it's more than stock.

A few folks have commented on the external sound being worse with valves closed. This is not a real world driving situation. No one considering this product is full throttle in stealth/valves closed. In every other mode the valves open at heavy throttle. And not only is there no drone, as mentioned above the car is quieter when cruising.

As with any louder exhaust, it's a personal choice whether you like the lower rpm and part throttle noise. You can select tour/sport/race exhaust setting to match your personal preference for when the valves are open. I now drive around in the Sport exhaust setting so I can enjoy all the different sounds but still default to valves closed in 6th on the highway.

Looks are subjective, but the combo of the carbon diffuser and the carbon tips look amazing. Could be OEM.

Bit of context: car is stock, other than Girodisc front rotors. I do HPDE events where the car is wonderful but found the powertrain emotional experience when stock a little lacking.

I've worked with Tapout Tuning for a few small items, the customer service is amazing, so I fully endorse using them if you want to buy this product. We in the Columbus area are very fortunate to have this technical expertise in our local area.

I will do my best to answer any questions either in this thread or as a DM.

Great post - thanks. I haven't listened yet but will do so at some point. For sure I will upgrade the exhaust...but not likely until next year sometime....we'll have to see...

Just your review and impressions of the Corsa alone have convinced me to consider it...
 
Nice review. Thanks for doing this!

By the way, we received the first production batch of Corsa CT4-V Blackwing exhaust systems and all preorders shipped today.

Thanks for your business guys!
 
I'm receiving part 2 or the shipment today and have plans to throw it on in a week from now. Bought it on faith that Corsa will put out a quality product and sound (I never trust YouTube vids to give a good idea of in-person sound) and it sounds like it was a good bet!!

Great review and thank you for posting it!
 
Today is the last day of our Black Friday Sale. We have all 18 part numbers of Corsa Blackwing exhaust systems in stock for immediate shipment at the lowest prices ever!
