Got rid of drone and rasp!!!
Sound excellent on my v6 camaro. It got rid of the rasp and drone even gives it a somewhat exotic sound vibe to it.

Exceded my expectations
Put on my 98 GMC seirra Z71 shortbed, regular cab, with brand new crate 5.7 vortec. Had true duels with no cats and two seperate flow master super 44s. Replaced the two super 44s with single Dual inlet, Dual outlet Magnaflow X-PIPE muffler. I was everything I was hoping for and then some. Its a bit quiter now but the overall sound is much better. More deep, smooth almost high performance v8 sound. I swear the truck has a noticeable amount of more power and seems to run smoother probably because the X pipe is evening out the flow, where b4 they never met. If your looking for a more deep distinguished high-performance sound as opposed to just loud, then this is the way to go. Fantastic Mufflers.

Drone Killer!
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.

Fits a 99 Chevy Silverado
It’s not too quiet but also not as loud as straight pipes yet still gives it a nice tone. The price isn’t bad overall but only thing I would complain about is that the welds could be better.. they aren’t as clean as the advertised photo.

Great option for true duals
Sounds great on my 4.6 and took away all the raspy clap I had with high flow cats and true duals. Blows my old flowmaster out of the water

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.

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.

Got rid of my rasp on my 2013 Audi s4 After building my own exhaust the rasp at 2000rpm was horrible after reading articles on Audizine form and what people are doing to resolve the rasp issues I thought I give it a try It worked as described zero rasp now Just a nice deep tone
