MagnaFlow X-PIPE Performance Muffler | 2.25 in. Inlet/Outlet

Works and fits correctly and sounds good

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.

I bought a used 2015 V6 Camarro that came with Flowmaster mufflers on the back. It sounded more like a souped up import than a muscle car and had a terrible drone right around 1700-2300 rpm a.k.a. highway cruising and wake the neighbors high idle. My wife was exhausted after a 1 hour drive and I got tired of setting off the car alarm in the little Honda that parks behind me. I added this muffled x pipe up stream and kept the Flowmasters in place. Nothing compares to the sound of a V8 with headers, but this unit took the raspy tuba out of the high range and gave it more of a growling idle. Definitely more "American" sounding. It stepped on that drone pretty good too. The obnoxious drone range pinched down to around 1900-2050 rpm and isn't as loud when it's in it. I still set of the Honda's alarm from time to time when he parks to close, but I took the wife on a 2 hour cruise through the mountains and she was happy with the reduction in noise. The car has a nice grunt when I step on it, but is much quieter in cruise, and if I use the paddle shifters to get further away from the droning range, it goes silent. I couldn't be happier with how this pipe balanced my car between daily driver and kept a good time when I want it.

Great sound, install these in your B8/B8.5 S4

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.
