This is a great muffler that is made out of really nice stainless steel and will last a really long time. The sound is perfect, not too loud but not too quiet either but it hasn’t fully broken in yet so it will get a little louder than it is right now but it’s not a loud muffler anyway. I installed my magnaflow muffler right in place of the stock one and got an extension to connect from the muffler to the tailpipe so I have all stock pipe. It sounds really good so far and once it’s broken in it’s gonna sound even better. I’ll include a video of how it sounds on my 5.7l vortec 350 in my truck.

Looking for 3" & 31/2** A: 3" inlet and 2.5" outlets **Q: you can make this dual exhaust right?** A: This muffler will allow you to make a single exhaust system into a dual exhaust system from the rear of the catalytic converter back.It is also a VERY GOOD replacement for factory mufflers in a single in/dual out setup.For instance, this muffler was used in the place of a factory muffler on a 2010 Dodge Ram Hemi - gives fantastic tone without being too loud. **Q: hello, is that Muffler overall length 24 or 20 inches ? because that number part 12288 description is different on the MagnaFlow website !** A: Always refer to the manufacturers website for the accurate information about there products. Internet sellers list many thousands of products. Every internet seller makes listing errors with pictures and content. The body of this muffler is 18" and 24" to the tip of the inlet and outlet. Thank you **Q: What modifications and/or extensions were needed for instalation since muffler is shorter than stock. And outlets are spaced farther apart???** A: I have a local dealer Mad Hatter in Fort Lauderdale Florida install dual exhaust after the muffler. They did a fantastic job. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is a great muffler that is made out of really nice stainless ... *by A***. on January 29, 2018* I installed this muffler on my 1996 Chevy Silverado and it fit well (with some slight modification).

Order the Magnaflow same size as other muffler. Bought some band clamps too no exhaust leaks and nice sound at start up, chill driving down the road sound. Nice aggressive sound at wide open throttle. Great replacement for anyone who doesn't want drone or too loud of an exhaust system.
