2014+ Exhaust Systems & Mufflers

Half_ton · June 2, 2015

To be honest i'd make sure you hear it in person before you order/modify exhaust on a V6. I talked with a guy about his exhaust at a gas station and it sounded great at idle and then he took off on a 55mph 2 lane hwy and it sounded like an old L36 3800 V6 with a fart can on it. Horrific!

Kind of hesitant to admit it bout I bought the DBL cab V6. It does everything I need and it's feels a lot better than I thought it would. Any suggestions on an exhaust or will they all sound cheap at higher RPM's? I've seen videos and they sound good at idle but I'm not sold on how will sound in V4 mode or even V6 at higher RPM's...... That in advance fellas. (I've had fully loaded V8's in the past but didn't feel like shelling out the extra cash this go around. I have a few other irons in the fire at the moment.....)

My v6 sounds good at idle. It doesn't not sound like a muscle car v8 when I step on it. I got a flowmaster muffler. No flappy valve either.

My thoughts exactly. Just thought someone who may have had more experience may have some useful info. It's hard to believe I can get anything close to the sound I want out of a V6. If that's the case I guess I just saved some money I spend somewhere else

How do you like the Corsa so far? What kind did you get, Sport or Xtreme? I'm looking into them, and I'm liking them more than the Borla alternative.

How's cruising with it? I want something that'll be more aggressive when accelerating and idling, but for the amount I drive, I still want to be able to not go insane. Guess I'm too picky.

My Corsa cat back is the Sport sound model; all of the 2014 - 2015 Corsa cat back systems for Silverado / Sierra 1500 trucks are Sport. They do not offer a Touring sound for these years/models. Check out the catalog at Corsa.com.

Yes, it is aggressive when accelerating, but when cruising, I can hardly hear it. Fit and finish is top quality and I couldn't believe how much lighter it is vs. the stock one.

Any suggestions on a tune that isn't stupid expensive like a black bear ?

Guys looking for some suggestions

I have a 6.2 and had the muffler chopped off almost a year ago. Left the resonator and flapper, and the sound was great. No drone, chopper sound etc

A few months later the flapper would act up and rattle like crazy very randomly. It drove me nuts, and more recently was getting a bit of a rattle for a few seconds at start up. Dealer won't warranty cause I've chopped the muffler

Anyway, had enough of it and wanted a new tip setup so took it into a shop a few days ago to have the tips done and flapper removed. They said removing the resonator wouldn't affect the sound much and needed to pull it to create the set up I wanted (two black tips side by side Corsa style) so I said fine

Picked up my truck alter that day and fired it up and its crazy loud, especially cold start. Its a bit too much. Piss off the neighborhood loud. For city driving its fine I could deal with it but I do lots of highway driving and the sound/more drone would be too much. Chopper sound isn't bad, but is there a little and the drone at some rpm ranges is worse

I'm looking for a muffler, probably Borla hoping to tone it down a bit and of course reduce possible drone. Any suggestions? I am also considering throwing the resonator back in where I chopped the muffler off originally to tone it down cause I think its a straight thru design and would fit. I should have paid for a cat back right off the bat but hoping I don't have to go that route now that I got new tips etc

What are thoughts or experience on throwing the resonator where the muffler was, or muffler recommendations. thanks

I just had the Magnaflow 12909 installed in place of the stock muffler. I had them cut off the flapper valve as well. Fit perfectly. Definitely louder but not obnoxious or anything. Very deep sound. Left the stock resonator on as well as the full stock tailpipes so I'm sure that quiets it down a bit.

I bought a couple feet of 3.5" pipe (just in case) but didn't end up needing it.

Looking for a very deep throaty sound, but not obnoxious. Don't want to spend a lot. Truck is a 2014 5.3. Have never heard the "drone" that everyone speaks of, so I don't know how I feel about that. Truck is basically stock. Any and all thoughts? Thanks guys.

I just put a Flowmaster Deltaflow 50 series on my latest Z71. Took first road trip right after and it wasn't bad at all. I have previously had a delete muffler then a Magnaflow 14 inch on my other 2014s. Cold start up is just right, AFM chopper not very bad, nice little growl when needed and with the Flowmaster baffling as opposed to the Maggie straight thru design you won't sacrifice any low end torque.

So I've had the 14" magnaflow installed for a few months now, about 4,000 miles. While it does sound good, I'm looking for something a little bit louder. Watched a bunch of corsa videos on youtube and I think that's what I'm after. What I'd like to do is just do a muffler swap. Does anybody know if they just sell the muffler?

Also, I haven't been able to find any good drive by videos of a corsa sport. Can one of you guys that has the corsa installed make a drive by vid? Really trying to hear it while hard on the gas instead of just a rev video.

You haven't heard the drone because you still have the flapper valve. If you remove it then you'll get a drone. The more aggressive and louder the exhaust is without the valve the more drone you'll hear.

snapring6r · July 1, 2015

Well with the flapper still in place, how can I get that very deep sound?

You disable AFM so it won't go into 4cyl mode and then put any muffler you want on it. As long as AFM is enabled then you are going to have unwanted sounds when it goes into 4 cylinders. Everybody is different on how they feel about the V4 drone but I have owned 3 other V8 chevy trucks with a flowmaster on them and love the sound but I don't think I am going to get that sound out of this truck till I tune out V4.

Kerrslight · July 1, 2015

Are there any exhaust mufflers that sound similar to corsa? Really wanting a corsa to replace my 14" magnaflow. Just don't want to purchase a full system.

Lol you go through mufflers like I go through shoes. Let us know what you go with. Some people have been lucky and been able to buy the Corsa Sport muffler by itself. I've looked around and can't seem to find just the muffler.
