2014+ Exhaust Systems & Mufflers

Trza · November 26, 2015

I just installed the Dynomax VT exhaust and I have to say that I am very happy with it. It's actually louder than what I was expecting since most of the feedback I've read on this forum has said that this system is too quiet. I did the install myself and it was extremely easy. To get the stock system off, I just jacked up the passenger rear, dropped the spare tire and wiggled it out. The hardest part was getting the exhaust off the hangers. I just WD40'd it and it definitely made it easier to wiggle loose. Install wise, this system comes in pieces with clamps to hold everything tight.

As for the sound / drone /V4 mode, you can't even tell that anything has changed. It has a really nice deep tone when you hit the throttle and quiets right down when cruising. Keep in mind that I also have the Airaid intake tube which I'm sure helped with the overall tone.

This exhaust was exactly what I was looking for. It's louder than stock, but not overly loud and sounds normal in V4. I'm actually shocked at how cheap this system is and was impressed with the fit and finish. Another positive is the throttle response! I had terrible lag when starting out from a red light...almost felt like the truck would lose power and kick back in. Now, it has a linear power delivery and can definitely notice an improvement in power and response. This is probably the biggest surprise since nobody has really mentioned if from previous reviews.

I did the exact same setup. VT system and Airaid intake. Great combo!

To each there own. This is what I did and I recommend it to everyone. Again I have a 6.2. Feel free to look at my other videos. This setup that I came up with sounds amazing.

VT has the chopper sound in V4 mode, mostly annoying at lower speeds.

My VT also had the chopper sound at slight throttle, very annoying when cruising down a flat 55 mph highway. Maybe the Airraid tube helps out with that, IDK. I love the sound of the VT had mid and wide open throttle but idle was very disappointing, almost like stock after the engine idles down at start up.

Sounds awesome......how did the header install go ? (timewise/difficulty)

It was easy

That borla sounds so damn good. I wonder if a shop would move the flapper after the the 3rd cat and run the pipe to that borla xr1 out to some nice tips.

I ordered a Carven Type R. Will probably be a few weeks before it's installed.

Consensus is to remove the resonator and flapper?

So after watching this and silver ice's video above i'm kind of sold on picking up an XR1 muffler, Y pipe, and then mandrel bent tubing into tips, angled split rear.

Remove resonator and flapper

Interested in the Carven - wondering if they make a 3.5" - with the flapper and res removed should sound pretty good..

I do not think they do. I believe they are only 2.5" and 3.0". Why do you want a 3.5"?

You could call them and ask if they could make a 3.5" for you.

kennerz · December 2, 2015

When it comes time I will do that. Just the factory is 3.5" and If you ran a complete cat back at 3.5" with no restrictions it should pick up "Something" (Who knows) HP wise. I went from a 3" to a 3.5" on a built camaro and it picked up a super noticeable amount of torque on the butt dyno. Car felt way more powerful. Went from a 3" 40 series flowmaster to a 3.5" race 14" magnaflow it was quieter, deeper and more powerful than the 40 series.

I just have to think the flapper, factory exhaust, & resonator offer some type of restriction. Carven had a dyno of a 5.3 silverado that gained something like 15 rwhp and 23 ft-lbs. to me that is pretty substancial for a muffler. (maybe has better scavaging). But the two I'm looking at for my 6.2 would be the magnaflow or the carven. I believe it's the AR-1 carven that sounds really bad with a great tone & no drone.

5.3L is 3" exhaust and 6.2L is 3.5" exhaust?
