MagnaFlow Performance Exhaust Muffler 12256: 2.5″/2.5″ Inlet/Outlet, 5x8x18″ Oval, Stainless Steel, Satin Finish

Purchased for a Jeep TJ 2006. Cut the ends from the factory muffler and clamped it on. Added 8″ of pipe to the rear and connected the tail pipe. Autozone parts. The tone is very deep and there is no roar inside at highway speed. Not much louder than stock but a soothing low rumble. Love it!

Not too loud.. not too quiet… straight through mufflers are the best for air flow and sound…I cleaned the throttle body and IAC thoroughly and Installed a spectre oiled air filter and new plugs and wires now I can tell the difference in idle and acceleration… I wasn’t expecting major improvements…after all the truck weighs in at over 5000 pounds empty… so I made the right choice..with magnaflow 12256 and 24 inch turndown… I used a micrometer to measure inlet and outlet sizes on my truck exhaust pipes… just to make sure…and double checked the new muffler to make sure that it fitted too…so I didn’t have to add all kinds of adapters and reducers and all that… nah!!! It just slid right on…. and bolted right up… do the homework… 5-24-20 UPdate: after 2 years later and it sounds even better; more of that throaty sound we like. No drone… I used u bolts and did not weld it on and they have held just fine without no exhaust leaks or looseness. I measured how much exhaust pipe to cut off and how long the tail pipe needed to be to extend past the truck cab and no fumes got into the cab. Do the homework.

Fantastic muffler 2.5 inlet & outlet. Solid construction. Tap on it out of the box and it feels and sounds Solid!! The packing inside is engineered to mitigate droning and raspy wide open throttle shrieking that can happen with four cylinder engines. Sound is at a very comfortable level and the neighbors dogs are happy too! Great product!!

Installed this on my 2014 4Runner SR5 with 4×4. The sound is very becoming of this SUV. It takes the 4Runner from a very quite, almost silent exhaust, to a nice low yet sporty growl under acceleration. The tone is perfect, and the volume level is perfect for a guy who wants to sound more aggressive, but can still use the Toyota as your family car or weekend grocery hauler.If you want an exhaust that you can hear all the time, even during idle, then get a smaller louder muffler. I used to to have a pretty loud exhaust set up on my BMW 330i ZHP so this was a step down from the volume that I’m used to. I’m very happy with this exhaust set up.
