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

## Features

*by T***. on 30 July 2019*

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.
