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 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).

Took the rasp out of the ls the kids love these days. No more annoying exhaust. Zero drone. Mid muffler fitment was perfect. Zero loss in performance just tone changed.

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.

Bought on a Monday, arrived on Friday. Great shipping, great product. Put this on a 2011 Ram 1500 and sounds better than my expectations. No highway drone, barely any sound at idle or easy driving but when you step on it opens right up to a nice bark. Only issue I had was the in/out diameters. It was not 3" like described. It was over 3 1/8th of an inch. Over all extremely happy with this. Would buy again.

I have a 2005 Dodge Ram 1500 5.7L, i purchased this over other mufflers because of its straight through design and not chambered like most so it wouldnt restrict flow. Sounds great, i get compliments all the time on how nice the truck sounds, its quiet on the highway, no droaning or excessive noise, and when you accelerate hard people notice! Love it and will buy it again for my next truck.
