2014+ Exhaust Systems & Mufflers

[CalicoJack76]

Put the Corsa Catback exhaust with dual rear exit tips on few days ago...

 

Excellent sound... Very deep rumble... No drone (AFM turned off before install) ... Not too loud even at WOT.

 

Big thumbs up for this system ...

I went with 3" from cat back into a flowmaster 40 then 3" to the 3 1/2" tip. Sounds good imo.

How is the chopper AFM sound with that muffler?

How is the chopper AFM sound with that muffler?

 

It's there but barely. Have had other truck guys say it's barely noticeable as well. One guy has a 2013 with single MagnaFlow and says mine has less but not sure if different year matters. I was hesitant at first getting a Flowmaster because I didn't really like the sound on my 87 Silverado with them but 2 months now and I'm happy with it. It actually gets a little deeper when it switches to v4.

Awesome! That's great to know as i'm looking to get the same mufflers on mine and was hesitant because of everyone talking about that "chopper" sound, even though I've never paid attention enough to notice before.

 

Thanks for the info!

Just an observation to pass on to those looking at exhaust changes...

 

I have a 2014 Silverado (Double Cab, Regular Bed) with the 5.3L and Corsa cat back, single side exit with dual tips. My son has a 2010 Silverado (Crew Cab, Short Bed) with the 5.3L and Corsa cat back, single side exit with dual tips. The Corsa systems are different part numbers, but both are "Sport" sound and same length. So, one could say they are both somewhat the "same" configuration.

 

Having set the stage...I am amazed how different the different generation of GM trucks sound. I know too well that there are a lot of differences between the generations having had a 2011 Silverado myself, but made the decision to buy the Corsa partially based on the quality and results of seeing / hearing it in person. While I am very happy with the quality and sound result, I just want to point out that it is different and to be aware of this when making comparison to previous generations.

 

Also, in reference to drone and the V4 chopper sound...my Corsa has NO drone, but there is a different tone that happens with V4 which I do not like. I experienced the same different tone on my 2011 Silverado with the Banks cat back performance exhaust which also had no drone. The only resolution to this V4 sound issue that I found that was satisfactory to me was to turn off AFM/DOD (either with Range device or tune) and then it sounded like a real V8 (because it never went into V4).

 

Not looking for comments...just thought I would share my observations in case it could help someone else. Really like the Corsa sound with AFM turned off ...the way I think a truck should sound...

The AFM is a killer for those of us who like a deep and mellow V8 sound. I been putting exhausts on my V8's for over 20 years, from loud to mild but this new generation truck is severely handicapped when it comes to a nice exhaust tone because of the V4. I was hoping the dynomax VT was going to be the answer but for me it was very dissapointing in both sound and the "chopper" sound at slight throttle in V4.

I just got done making a (in my opinion) great exhaust video to show the sound with a 14" magnaflow. I was asked by another member, but I have also been meaning to do this for some time now. When I was looking for sound clips to help me make my decision, it was a pain in the ass finding a good video. I've had my muffler now for a while and I love it. I think the only other way I would be happier is with a corsa, but I love this for now. Video is uploading as we speak. I will post it when it is ready.

where the vid?

where the vid?

Impatiently waiting for it to finish uploading to YouTube. I recorded in 1080x60 so it's a large file

[Kerrslight]

Here it is....finally

What Wendy's said. Delete flapper and resonator. It sounds great. You will be happy with it.

Is the resonator the last little muffler looking thing Right before it exits?

Your truck kinda sounds like a sport bike from inside the cab, under normal acceleration :-p Edited July 18, 2015 by TDT

Yes it is.

Haha I see what you did there

I have the v6 with a flowmaster super 40 but still have the resonator, no floppy valve, you think if I remove the resonator I'll get a deeper growl? What about drone? I know v6 :-( lol

[iCryWheniGoPoop]

I'm tossing around the idea of a 22" or 18" today. if I find one in town I'll report back on which way I went
