MagnaFlow Performance Exhaust Muffler 14419: 3"/3" Inlet/Outlet, 4x4x14" Round, Stainless Steel, Brushed Finish

I purchased this to replace my stock muffler on my 2012 4.8L Silverado. I had my local shop install it, only took them about 15 minutes. It does drone a bit inside the cab at certain RPMs, but that's because I have the exhaust dumped just before my axle. But it isn't obnoxiously loud. It's more quiet than my '95 Sonoma (2.2L - 4 cylinder) with a gutted interior and straight pipe exhaust, with the same style dump. Can still hold a conversation without yelling over the drone, and can still listen to music, no problem. The idle is nice and low, with a nice rumble, but definitely opens up and screams when getting on it. Definitely sounds like how a v8 should. Glad I chose Magnaflow. (PN - 14419)P.S... I just had it installed today. (May 2022). From what I've read, they will get a little louder and give a deeper tone once fully broken in. I'll do another review to give my thoughts and see if there are any changes to the sound quality. So far, I'm happy with the purchase.9 months after install: (Feb, 2023) Still very happy with the purchase. The sound is still very crisp and I noticed the tone did get deeper and is more refined. The sound did get a bit louder too, but still not obnoxiously loud. Even with it dumped before my axle, the drone in the cab still isn't that bad. I can still hear my music and can still have a conversation without having to yell over the drone. Also, when cruising between 35-45 the exhaust sound is almost non existent. But when I get on it, it really opens up and screams. I'm very happy that I chose Magnaflow (PN-14419) for my 2012 4.8 Silverado.

The price was very reasonable. I installed the muffler myself and I was amazed at the sound. I really like it and so does all my buddies they say it really sounds good going down the road.

I received the muffler in like 3 days came nice a sealed and these sound pretty good

It looks cool it was made very well pretty controlled drone

The media could not be loaded. I put it on my Silverado 2006 engine 5.3 and I liked it, it's not an irritating sound and when you go at constant speed on a highway it's quiet but when you accelerate it sounds very good and not noisy

I ended up returning mine as I didn’t like the sound. However, it was packaged well and was as advertised (aside from not being shiny like pictures). Mine did appear to be used as there were dents from someone clamping it previously. However, this didn’t affect anything and I just clamped it in the same spot. I switched to an oval shaped model and am very happy with it (also magnaflow).

Great muffler. Sounds great.

Bought this for 2011 f150 with the 5.0. After getting it put on I instantly regretted it. First of all this is a loud muffler but thats not my complaint, this muffler will pop real bad when when you gun it and when your truck is down shifting, which sounds bad in my opinion. Ive already swapped this muffler out with the thrush wielded muffler and im very happy with. I had this similar muffler on my 07 dodge hemi but the 6 inch round one, instead of this 4 in round and it sounded real good, thats why i wanted this muffler but these did not sound the same at all.
