Pro Flow Straight Through Mufflers 4th Gen Toyota 4Runner

The Pro Flow straight through mufflers deliver strong exhaust flow with a clean, deep tone. These mufflers use trusted MagnaFlow technology with a fully welded stainless steel body that resists rust and heat over the long haul. 

You can choose between a 2 1/4" and a 2 1/2" inlet size depending on your existing exhaust setup. For drivers who want a slightly quieter note while still gaining performance, the 18" body length is available in the 2 1/2" size.

4th Gen 4Runner Muffler Finish Choices: Satin vs Polished

Each Pro Flow straight through muffler comes in your choice of satin or polished stainless steel. Here is what sets them apart:

• Satin finish offers a clean, understated look that blends naturally with a stock or mildly modified undercarriage
• Polished finish delivers a bright, show ready appearance that stands out under the rig and pairs well with custom exhaust builds

Both finishes use the same fully welded stainless steel construction, so the choice comes down to your personal style and how your 4Runner is set up.

Pro Flow 3 Chamber Mufflers for Your Toyota 4Runner

If you want a deeper, throatier exhaust note, the Pro Flow 3 Chamber mufflers are worth a close look. The packing free design uses internal chambers to tune the tone rather than sound deadening material, which means performance stays consistent and does not fade over time the way packed mufflers can. 

These are available in both 2 1/4" and 2 1/2" inlet sizes and are a popular pick among enthusiasts who want their rig to sound as capable as it is.
