Sounds great on my 2009 Ram. Not too loud. Fit good with a bit of welding and cutting.

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.

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.

I was looking for full, duel exhaust since I bought the truck in April. I wanted something to add little more low tone and just more lively then stock but didn't wanna be "that guy" waking the neighborhood up when you drive by or start it. I also didnt see a point in spending $1000+ for a full dual system when my current was doing the job. Middle ground is buying a muffler and putting it on the stock pipes, so I did that. Great sound especially at lower speeds, could be considered slight drone in certain gears and rpm but not bad. When stepping on it combined with the Specter Cold Air intake makes the truck sound come alive. I also seeing a +1mpg currently which is interesting. No torque loss (according to my butt dyno). One review hear says its the goldey locks of mufflers. It really is. Put on a nice looking tip and called it a day. Aftermarket sound and look for $290 with install and the tip.
