M&K Exhaust mufflers are simply the highest quality muffler available on the market today.

Each M&K muffler is built with handcrafted tig welded perfection that NO Other exhaust manufacturer can compare.

Each muffler is specifically tuned to maximize performance and sound.

Why choose M&K?

Each M&K muffler is produced utilizing 321 stainless steel. This type of stainless is commonly used in the aviation industry due to it's higher quality alloys which withstand high heat applications. M&K are the only manufacturer to offer 321 stainless exhaust systems for Porsche automobiles.

Why 321 and not 304?

304 is not as durable as 321 in handling the constant heat cycling exposure produced during the lifetime of an automobile. 304 is also not as resilient as 321 in withstanding the acids given off by an internal combustion engine. Over the years 304 will eventually deteriorate and lose its strength and eventually need to be replaced. If your looking for a muffler that truly will last a lifetime then 321 stainless steel must be your choice.

What M&K do different.

M&K mufflers are designed to create a scavenge within the shell of the muffler to draw the exhaust out of the engine as quickly as possible. This allows your engine to breath better and create enough back pressure to increase the performance of your engine.
