My 2014 CTD vs 2015 CTD

Hey there. So I recently bought a used 2014 Chevy Cruze Diesel for a good deal. My friend has a 2015 Chevy Cruze Diesel aswell and I notice whenever I’m with her her’s exhaust note is deeper and has way less clatter. Is there any reason why mine has way more clatter and doesn’t sound as good as hers? I just love the way hers sounds and I just want mine to sound the same.

I’m not aware of any mechanical differences between the two years. AFAK the differences are purely cosmetic.

What are the odometer readings on the 2 CTDs you’re comparing? Is there a significant difference in km driven?

Yes, mechanically they are identical...

Mine is 146k km and hers has 137k km

Hmm, no significant odometer differences. Theoretically they should sound identical, assuming there’s been no other mods done and no damage or worn components.

I know right. And like mine doesn’t sound bad but hers has a deeper growl and yea. It frustrates me that hers sounds so much better.

It's possible something in the exhaust was changed along the way. 2011-2012 gas models had a different resonator than later gas models. I'd think for such a short-run, limited-production model, nothing would have changed.

No mechanical differences between ‘14 and ‘15 CTD.

From personal experience, the type of oil and type of fuel can make a difference in the sounds CTDs make.

But I suspect that one of the two cars has been modified from stock.

Most likely the sound absorption foam, beneath the engine cover, has been removed or otherwise compromised on one. As well, it’s possible that the induction system on one has also been modified from stock.

Maybe hers is deleted?

It’s probably the location that you’re sitting in the car. Drivers seat in your car vs passenger seat in the other one. Where you sit in a car can make a big difference in the way you hear it sometimes.

No hers is not deleted I’m sure of that.

I have driven hers aswell a few times and just for a minute or two. It’s been trips to the city and such. It just sounds so much better and it bothers me haha

Yea ours are both stock. It’s really bothering me that hers sounds so much better

Are you hearing hers warmed up & yours is not by chance? Mine sounds "angry" when it's cold out. By that I mean it's louder, sounds a bit fiesty, and in general like the bad ass Racecar she is. After she is up to temp it calms down a bit.

My friend's & mine are identical years & I still feel they sound a bit different. Yet, I haven't had them both running next to each other.

congrats on your purchase btw, they are little beasts.

Your car needs an oil change

I'd be more jealous of the door lock button on the door itself and the trunk button on the console lmao

On that note the 15 MY did delete stuff but not sure if they did diesel wise since they both are 2LT trim level. Lit vanity mirrors, WiFi, (that door lock mentioned above) and dash glove box delete is the only thing I can think of off the top of my head. I guess the best way to compare is the "Do Not Remove" stickers in the glove boxes with RPO codes. That may list or not list a 2LT insulation package. I still haven't came across a diesel with the claimed Acoustic laminated side glass.

Nope. I have mine warmed up and hers is warmed up. We’ve had them side by side. And I just do not know why hers sounds better.

I notice whenever I change my oil the clatter goes away and the exhaust note gets deeper. That’s why I suggested it?
