Product Details

Universal 409 SS Round Straight Through Natural Muffler (12867-FM) by FlowMonster™. Muffler Inlet Diameter: 3". Muffler Outlet Diameter: 3". Muffler Body Length: 14". Muffler Overall Length: 20". Muffler Sound: Moderate. Muffler Configuration: Center - Center. The Flowmonster series of absorption style mufflers deliver a moderate tone for the enthusiast looking for a deeper, more aggressive exhaust note than most OE mufflers, unlike the racey exhaust note associated with "chambered" style mufflers.

Interior construction features 3.50 inch "straight-through" perforated 409 stainless steel tube surrounded by high-temperature sound absorption packing material which helps to deliver a deeper, mellower exhaust note. The internal design is reversible allowing the flexability to be installed in either direction to best accommodate fitment with the intended vehicle. The fully MIG-welded 409 Stainless Steel material is embossed with the "FLOWMOSTER" logo on the case.

Sounds Like a Boss
Now I have the deep sound I’ve dreamt about!!! I like the aggressive tone. The muffler is made of tough steel and is super rigid. So I am confident it will serve me no matter what. The muffler is colored in trendy silver. Have only positive feedback.

Totally Impressed with This Exhaust
I always wanted to make my car sound more beefy. Finally, my dream is a reality. Woohoo! I can't stop enjoying the deep and loud sound produced by my new muffler. More than that, I’ve noticed power gains. I’m sure this exhaust will serve me for many years - FlowMonster uses high-quality steel.

Total Transformation
I’ve made my car sound like a “monster” for a fraction of the cost. This affordable muffler is a true find. I chose it since it’s made of high-grade steel and MIG welded. So, this muffler is tough and rigid, and functional!!! Glad with my purchase.
