CT5-V Why is the exhaust so quiet inside?

[dinkman]

arent you guys worried about voiding your drivetrain warranty on a $100k car just to have a little more sound? i know the burden of proof is on the dealer if they want to deny a warranty claim due to modifications but with aftermarket headers that doesnt seem like it would be hard to argue. cat, or even axle, back exhaust not so much I guess

An exhaust won't void your warranty. The headers can certainly void the powertrain but the burden of proof is on them to determine they were the culprit.

Ultimately I would probably just go with the Corsa exhaust.

Its unfortunate the car is so quiet inside. If they made a Chevy version of the Blackwing it would be the one to have, less insulation and sound deadening and still drives great.

Would probably sell more of them as well.

Of course they would sell more because they would be same car 25k cheaper!

In my experience, I've had no issue with cat-back systems from the dealer. Obviously, if something is amiss with the exhaust system, that's my issue. But from cats-forward, to include O2 sensors, that would be covered unless they can prove my cat-back caused the failure or malfunction.

All that said, on my first visit to the Caddy dealer, my service advisor told me my transmission issue was not covered because I installed a blower... to which I had to explain to them that GM installed it from factory. YMMV

Wait.. he said your STOCK blower was aftermarket? Did he not know they were supercharged from the factory? lol

The only thing that was changed was the lid, which is blue. Otherwise stock blower. I think the lid threw everyone off. Either way, after a couple conversations explaining the BW was SC from factory, the lid was cosmetic/sound, some googling on their part “MPI LT4 lid” they moved on with the repair.

Was funny though, when they were closing out the work order, I saw they had printed out several pages from the MPI website about the lid and attached in to the work order file.

So I finally got around to test driving a ct5 v blackwing. It’s been on my mind to upgrade since forever and with prices going down a little I am contemplating a used one at some point.

The car just feels like a 1.2x ct4 so that’s great handling wise etc. but my biggest disappointment was the exhaust note inside the car.

Did a few rips up and down a straight and the sound was fine? Albeit the volume was too low for my liking. It sounds spectacular outside but inside it’s all smooth. I dare say I think the ct4 has more noise inside the car though they’re mostly obnoxious pops and bangs.

I think I still want it but it’s a bit of a dampener.

Ps- opening the windows just had a lot of wind noise and buffeting.

Roll down the windows lol

 

[PrimeTime]

I am slapping some of that Corsa junk on mine!

Have my eyes and ears on Corsa, waiting a bit for magnaflow to step up with a BW build and compare if it comes to pass. Anyone hear anything? Possible?

 

[FLYARMY]

Roll down the windows lol

Flip down the back seats, too.

Wait for a sale they always have them. I can't comment on mine as my lazy arse has it unboxed just sitting there...

Seems to me they did make it: the Camaro ZL1. SC V8 (same one?!), louder, cheaper. Still "has" back seats.

Probably best bang for the buck sports car imo. Just a few years ago you could get a ZL1 for 70kish? Jeesh, even better bang for the buck than a Corvette the king of BANG-FOR-A-BUCK!

 

[XjonesX]

Yeah that’s probably it.

Just to be very clear. I want more noise(hopefully pleasant) inside the car. It’s plenty loud outside.

And the seat thing while valid beats the point of having a sedan.

yeah..., I get it..., you want your cake and eat it to.
When getting up the road, I like it in tour mode and quiet, however when going through tunnels, under overpasses, and between tall buildings..., I always hit the "V" button for that awesome rumble and pops. Not my normal thing, but when I do..., do it..., I grin and chuckle like a 13 y/o boy seeing naked boobs. But loud exhaust has never really done it for me..., it's always been induction noise, as opposed to exhaust.
Nothing like hearing a V8 whipple charger spooling up at full throttle.
Back in the day growing up, I used to flip the air filter lid upside down on my 400cu rochester 4 barrel, and it was just so cool to punch it, and hear those 4 barrels open up and go "Whhhoooooomppp!" People on the street, as I was passing would always look up to see what it was.
You would always knew when the cops were going after someone as well with their huge engines, and 4 barrels...., you would hear the same sound.
I digress..., yes, I like a quiet cabin more times than not..., because I'm old. But I do love the sound of a forced induction car.
