DC Sports Round Muffler, 3" Inlet / 3" Outlet
If you want a true 3" round muffler with matching inlet and outlet diameters, this is the one. The DC Sports universal muffler (SKU: DCMU-300-R) uses a straight through muffler 3 inch core, so it flows like it should and does not feel like an OEM suitcase muffler choking the car. On a typical 3 inch setup, you can expect cleaner top end pull and quicker throttle response, plus a deeper note that sounds like an exhaust, not a vacuum cleaner.
DC Sports builds this DC Sports performance muffler from T 304 stainless steel with a polished shell, so it holds up to heat cycles, road grime, and daily abuse without turning into a rusty science project. Call it what it is, a polished exhaust muffler that is meant to get used. This DC Sports exhaust muffler also keeps exhaust velocity up thanks to the straight through layout, which is the whole point of a high flow exhaust muffler.
Fitment is straightforward for a custom system. This round muffler 3 inch inlet and 3 inch outlet works anywhere you run 3 inch pipe, NA street cars, turbo builds, or anything in between, as long as you have room for the 6 inch round body. Think of it as an easy DC Sports exhaust upgrade when you want a compact can that still acts like a real performance exhaust muffler, not a tiny restriction.
Let us be honest, this is a loud exhaust muffler compared to stock. Volume depends on your whole combo, headers, cat, resonator, pipe length, and where you mount it, but wide open throttle will get everybody's attention. If you pair it with a decent resonator and keep the rest of the system sensible, it sounds aggressive without feeling like an uncontrolled straight pipe.
We have run this exact DC Sports race muffler on our own vehicles, and it is a solid way to finish a custom exhaust. If you are hunting for an aftermarket muffler 3 inch outlet that actually matches your piping and does not bottleneck the system, this DC Sports exhaust muffler fits the bill as a universal exhaust upgrade and a universal muffler 3 inch option.
