Vibrant StreetPower Round Muff 5inx9inx14in long Muff body 4in inlet I.D. x 4in outlet Center-Center

If you're fabricating a custom exhaust system and need a muffler that offers a deep tone without restricting flow, this Vibrant StreetPower universal muffler is a solid choice. It's designed to give you a lot of flexibility during installation, letting you route your exhaust exactly how you need it. The "True Straight Through" design means exhaust gases can exit freely, helping to maintain engine performance.

This muffler is built from 304 stainless steel, which is known for resisting corrosion and holding up well over time, especially important for an exhaust component. Inside, it's packed with multiple layers of sound-absorbing material to effectively control drone and give you a low, deep exhaust note. The 4-inch inlet and outlet are center-mounted, and the muffler body itself measures 14 inches long with a 5-inch diameter.

Since this is a universal muffler, it's intended for custom applications where you're building the exhaust system from scratch or significantly modifying an existing one. You'll need to plan for hangers and connections based on your specific vehicle and desired setup.
