    • Nice mellow tone with little drone
Quality muffler, looks great and has a nice mellow tone. Perfect for someone who wants some noise but doesn’t want to be screaming everywhere they go. I bought this to replace an MBRP muffler from a 3rd gen Tacoma cat back system. The MBRP was too loud and droned too much for my liking, this muffler toned things down but still makes some noise. If anyone is making this same switch, I had to cut about 3 more inches off of the forward pipe before I could clamp this one in place. ... show more

    • MagnaFlow pn#12579 is "Y" core design.
Just got the package New Year's Eve. Had Ace Muffler Shop in National City. San Diego weld it up. Great Job guys,same day install. They said it should take 30 to 45 days of normal driving for the core packing to ware in and get resinie.. I got the full length 12579 Y core when i ordered it i thought i was getting straight core. 22" it will still be quite in my chevy cab to use Bluetooth hands free stereo... If you want to go loud get one smaller. If they have to add pipe to compensate for smaller muffler you will pay more for fabrication welding and hangers anywhere you go. Im not building a hot rod so this is perfect for my needs. ... show more

    • Nice mellow rumble at idle
I bought this to replace a muffler in a competitor's performance exhaust on my 2002 Chevy Suburban. That muffler wasn't loud initially, but became extremely loud after adding longtube headers with no cats. I installed this Magnaflow muffler in place of the other one, and the difference is night and day. Nice mellow rumble at idle, and a good sound when you hit the gas. No drone on the freeway either, my kids can still watch movies in the back seat with no issues. The only down side I could see with this muffler is its size and weight. It is pretty large and fairly heavy. It doesn't matter under my truck, but I don't see it fitting under a car very easily. ... show more

    • Very quiet muffler
I installed this muffler on a '95 F-250 with a 460 big block in conjunction with a QTP electric cutout. The goal was to have a stock sounding, but free flowing exhaust with the option for straight pipe dumps. The muffler does an excellent job. The truck is just as quiet as it was with the stock restrictive muffler and 24" long (very) restrictive catalytic converter however, the straight through design makes for very nice flow characteristics which have not impacted my power at all. Highly recommended for those need a quiet but free-flowing muffler. I've had the muffler on the truck now for almost 9 months. The stainless steel has discolored slightly from heat as well as holding road grime, but it appears that it's a nice high quality stainless that is not going to rust itself. ... show more

    • Great Muffler - Reasonable Price
I bought this to replace the same product I bought 14 years ago. I had a backfire that blew out a seam on the 14 year old muffler; otherwise it was still good. Happy to have brand new Magnaflow products in the system. 3" in and out, 22" length. Use: 1995 Suburban 454

I had a 18 inch muffler before I bought this one. This muffler has the right loud sound according to my wife.... so, happy wife... happy life.

    • Very mild sound.
Very mild sound. I put this on my 1998 Ford Expedition 4.6L. I was more interested in a better flowing muffler and didn't want anything loud. I do have a bit of interior drone when accelerating, but it's not that bad. I would buy it again.

    • Way to loud for me.
Nice looking product and well made, though It is at least as loud as the 70 series Flow-master I replaced. My ears are ringing as the 3" exhaust system on a crew cab resonates like nobody's business. Going back to the stock system.
