Purchased this to replace the factory muffler on my 2003 Silverado with a 5.3 (LM7). Wanted a bit more performance (also adding a cam, CAI and tune) without much more noise. This fits the bill. Barely louder than stock at idle with a nice bass tone under acceleration. There is the slightest of drones if you really listen for it, but I''m pretty picky and like the sound.

Added these https://www.amazon.com/gp/product/B07G95999F/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 to the order and the old muffler cut right out and this one fit right in it''s place - about 1 hours work using 2 3" and 2 2.75" heavy duty exhaust clamps (will likely weld it up later).

Magnaflow recommends the shorter one as a stock replacement, but if you want the performance without the added sound, I recommend this one.

Video is stock muffler, no muffler, Magnaflow with a stock Chevy 5.3. The tone has "matured" a bit since installing (videos taken as I was doing the work) but still really close.

Bought the stainless steel model for 04 Yukon 5.3 to compliment a new aftermarket cold intake & to help gain a little low-end torque for towing, had it installed at local muffler shop, its not too loud on start up or when cruising, it does have a nice rumble at idle and sounds awesome on acceleration, also this muffler or the intake seemed to help improve some stumbling from a dead stop, lifetime warranty, very pleased with the purchase!

This is for all you Chevy owners who bought a 20 or 21 Silverado with a 6.2. I have done some major experimenting on 2021 Silverado Trail Boss with the 6.2 starting with a 14" Magnaflow and flapper delete (came with only one). It was obnoxiously loud and had a terrible drone at highway speeds. I then put a 18" Magnaflow with the flapper back on and it was much better but still had a noticeable annoying drone at highway speeds. I finally installed a 22" Magnaflow (part #12589) without the flapper and it has a perfect tone and most importantly no drone at highway speeds. It sounds awesome at WOT! ***Total cost for all parts/labor at a reputable muffler shop near me was $495 which includes me keeping the 18" Magnaflow. Still significantly cheaper than any of the cat-back exhaust systems on the market. Hope this information is helpful!

this muffler is excellent on my 04 silverado with 4.8 V8. it has a noticeably louder idle, but not too loud, it has a nice little rumble when cruising, and sounds nice and tough when on a hard acceleration. It has minimal drone on the highway and when going up hills. If your looking for a little more oomph from your exhaust, but don''t want to put up with a loud exhaust on your daily driven truck, then this is definitely the muffler for you

I''ve been using Magnaflow mufflers for over twenty years. The stainless is high quality the welds are perfect and the sound is what I like. Quiet on idle and cruise, but sounds mean on hard acceleration. I went with the 5x11 body because I lean to the quieter side. The 4x9 would sound really mean. You can''t go wrong with these.

Product works great and sounds awesome. 2001 Yukon XL, no cat, got rid of my drone I had with my flowmaster, quieted down for normal driving, still sounds mean when on the gas hard. 4 stars because first one came with a big dent and sent for a replacement. Replacement looked great except one of the welds holding the center pipe to the case was just not welded. Rather than send for a replacement I opted to just weld it myself before throwing it on the truck and welding it all together. Very happy with the performance so far. Definitely will look to magnaflow over flowmaster in the future.

A little extra rumbling
Reviewed in the United States on September 18, 2021
Put this on a Ford e350 van with the 5.4L. Absolutely love the sound. Barely noticed at idle and a nice note under acceleration. Zero drone at highway speeds but a good healthy rumble when you kick it down to pass or pull away from a stop.

Worked out well On my 2004 Silverado 5.3
Reviewed in the United States on September 18, 2020
I like the sound but I am undecided between this or a thrush glass pack. Thrush being about a 1/3 the price I would have probably went with thrush. But I''m old school from the 80s. the Thrush sounds better at Idle this one not much different than factory till about 2000RPM.
