Description
The Mishimoto MMEXH-MF-3COBR is a universal 304 stainless steel muffler built around a perforated, fiberglass-packed straight-through core, paired with a 3-inch inside-diameter inlet and outlet in a center-inlet, offset-outlet configuration for flexible pipe routing. Finished in a brushed satin stainless steel with precision TIG welds, it’s designed to tame exhaust volume without choking flow.
Whether you’re building a custom exhaust or refreshing an existing setup, this Mishimoto muffler lets your engine breathe freely while cutting excess drone. The straight-through perforated core reduces backpressure compared to a baffled design, so you get a cleaner, more aggressive tone instead of a dull commuter-car hum. The 304 stainless steel body and TIG-welded construction are built to withstand harsh underbody environments, and the satin-finished exterior adds a clean, understated look to any exhaust system.
Vehicle Applications
This muffler is a universal-fit component rather than a vehicle-specific part, meaning it isn’t tied to a single make, model, or year. Its 3-inch ID center inlet and offset outlet are sized to integrate into custom or aftermarket exhaust systems built around 3-inch piping, giving fabricators and DIY installers the flexibility to route it into a wide range of exhaust layouts.
