Review: 2011 Mercedes C350 I used this together with the Magnaflow 10791 Tru - X Stainless Steel 2.5" Exhaust Pipe to delete the secondary Cats and Resonator. I got a little extra power and the sound with the stock mufflers is actually very pleasant. Just the right amount of growl and quiet as a mouse cruising around the neighborhood. PS> Yes I went 2.5" instead of 2.25" on purpose. It produces a lower tone and sets up the Header replacement which will be 2.5" out the new High Flow Cats.
Review: Sound excellent on my v6 camaro. It got rid of the rasp and drone even gives it a somewhat exotic sound vibe to it.

### ⭐⭐⭐⭐⭐ Review
*by C***A on 9 November 2023*

I straight piped my ride along with an added ecu tune with added crackles and pops. it was way too loud at very low rpm and sounded horrible being an automatic transmission car. I slipped this magnaflow back on to where my original mid silencer was. Perfect fit! The sound now is perfect. I love the deep sound. Reminds me of my old cat back magnaflow VW VR6 I had back in the day. I'm now not worried about driving in my neighborhood or watching out for police anymore Only thing I don't like now is that my car doesn't make loud gun shot sounds any more from my tune 😜 just some nice rumbling.
