Old stock
Quick delivery as always. However I ordered multiple for a custom setup. One as you can see is clean on perfect packaging. Shiny metal etc. The other looks like a box from the 90's that's been under water in the back of a warehouse and the muffler is all dingy and tarnished. I didn't expect that at all. I'll have to get another for this project because the exhaust will be visible. The rest look great and will work perfectly but this one is just very old stock. Not even a legible label on the box and the old school logo on the product. Still useful just not on this project

Great product! Sounds good on a 6.0 Sierra
So far I am really happy with this muffler. I bought it to replace my dual chambered mufflers on my 02 sierra 6.0. I used it as a dual inlet, single outlet setup. I was concerned about drone at hiway rpm but there’s nearly nothing. I was also wanting to quiet the truck down a little but not lose that rumble which this does perfectly. It looks great too. The only thing I’m not sure of is how it’ll hold up to salt on our Alberta roads in the winter but since it’s stainless it should be fine.

Great Muffler
Not too loud, not too quiet, just right. Great performance, noticed an immediate throttle response improvement. I put this on a 1999 4.0L Ford Explorer SOHC. It will fit (with some modifications). Not a direct fit, but if you use a couple of exhaust pipe adapters (and a bit of cussing) it will work wonderfully.

Not a exact fit extra modification needed
Love the sound. Not obnoxiously loud but enough throaty deep pitch on my ram to satisfy me. Not loud in cab either. Downside is they had to do some extra work to get it to fit so extra pipe was needed which meant a bigger price tag on the install. Still, worth it for me. I’m happy.

Great performance
I bought this for my project because of what I'd heard about it being one of the best performing mufflers, being straight through design and all. I know dynajet or somebody has the same kinda thing, but its also much more expensive being packed with fiberglass. This gives the same result, and even on a 4.0 v6 the sound is still pretty cool at that. Great purchase, and especially it being stainless I'm definitely happy I bought it.
