MagnaFlow Performance Exhaust Muffler 11386 | Deep Signature Sound, 4x9x14" Oval, Stainless Steel, 2.5"/2.5" Inlet/Outlet, Dual/Dual

Works and fits correctly and sounds good

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.

Chopped out X pipe and replaced with this. Drone , rasp, and popping gone. Quieted down substantially when added to the borla axle back touring . VERY DEEP and RICH at part throttle and idle. Screams like an LS should when ya crack it. Wish audio was better on video..... Sounds amazing! 2012 Camaro SS . Heads, III BTR, LS3 valvetrain, long tubes cat-less, DOD delete, Circle D 3200, 373 gear..... smile extra large

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.

Removed the stock mufflers and resonator and used this xpipe muffler to replace the stock X pipe on my 09 Maserati Granturismo. Wasn't about to pay several thousand for a Larini exhaust. Some drone right at 2100rpm but otherwise no drone at any other RPM. Fantastic sound, opens things up and makes it truly sound like a 4.2 Italian V8. Deep and aggressive but more refined than an American V8 (not that there's anything wrong with that sound either) muffler build quality is excellent, which is to be expected from Magnaflow. Excellent welds and stainless steel, not worried about longevity. Magnaflow is always more expensive than it should be but it still beats the alternative. No noticeable power change either direction.

I'm completely sold on Magnaflow. I have used their mufflers on many vehicles and I have always been very happy. I was very skeptical about running dual exhaust with this X pipe configuration, on my 996 twin turbo, but after installation with 200 cell sport cats, I am more than pleased! They sound better than I ever imagined and with no notable performance loss going from straight pipes. They have no drone or rattle and the sound is so sweet! I love this muffler! Thanks Magnaflow! They are 2 1/4 inch which matches my factory exhaust tips. Some people say you need a larger diameter to get a nice low note, but this sounds prefect to me. I'll never change my exhaust. Found what I was hoping for. 5 stars well deserved.

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.

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

Estoy muy satisfecho con la compra de esta X-pipe de Magnaflow. Realmente le da un sonido mucho más agresivo al motor, pero al mismo tiempo mantiene un tono limpio y sin esas vibraciones molestas. Es una mejora totalmente recomendable si buscas un sonido deportivo sin perder calidad.

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.

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

Happy with the product as promised.

Fricken sounds beast !!! Had a muffler shop run me a custom install using this muffler. Get a lot of comments on how great it sounds on my Lincoln LS V8. Really sounds awesome when you get on it. Good quality product, very pleased with purchase.
